  • POP Forums v9 Beta 1 for ASP.NET MVC 3 posted to CodePlex!

    - by Jeff
    As promised, I posted a beta build of my forum app for ASP.NET MVC 3. Get the new goodies here: http://popforums.codeplex.com/releases/view/58228 This is the first beta for the ASP.NET MVC 3 version of POP Forums. It is nearly feature complete, and ready for testing and feedback. For previous release notes, look here, here and here.Check out the live preview: http://preview.popforums.com/ForumsSetup instructions are on the home page of this project. The new hotness in the beta, or what has been done since the last preview: All views converted to use Razor E-mail subscription/notification of new posts New post indicators/mark read buttons Permalinks to posts Jump to newest post (from new post indicators) Recent topics Favorite topics Moderator functions for topics (pin/close/delete, plus move and rename) Search, ported from v8. Not a ton of optimization here, or new unit testing, but the old version worked pretty well User posts (topics the user posted in) Forgot password Vanity items (signatures and avatars) Hide vanity items per user preference Some minor data caching where appropriate A little bit of UI refinement Lots-o-bug fixes Lots-o-unit tests What's next? The plan between now and the next beta is as follows: Continue working through features/tasks, and fix bugs as they're reported Integrate the forum into a real, production site Refine the UI Refactor as much as possible... the code organization is not entirely logical in some places After the second beta, a release candidate will follow, with a real "final" release after that. Subsequent releases should come relatively frequently and without a lot of risk. The trick in building this thing has been that it mostly tossed the previous WebForms version, which was all full of crusties. The time table for this is a little harder to pin down, as day jobs and families will have their effect. Other notes Refactoring will be a priority. As the features of MVC have evolved, so have my desires to use it in a fashion that makes things clear and easy to follow. I don't even know if anyone will ever start mucking around in the code, but on the off chance they do, I'd like what they find to not suck. Other nice-to-haves are builds to target Windows Azure and SQL CE. A nice setup UI would be super too. I think the ASP.NET MVC world has gone long enough without a decent forum.The biggest challenge that I've found is making the forum something that can be dropped in any app. While it does rope its views into an area, areas are mostly just routing details. I haven't thought of a clever way yet to limit dependency injection, for example, to just the forum bits. I mean, everyone should be using Ninject, but how realistic is that? ;)How much time and effort should you spend on POP Forums in its current state? Change is inevitable, but at this point I'm reasonably committed to not changing the database schema. I really think it will stay as-is. All bets are off for the various interfaces throughout the app, but the data should generally resist change. It's not even that different from v8, which was one of the original goals because I didn't want to rewrite SQL or introduce a new ORM or whatever. My point is that if you wanted to build a site around this today, even though it's not entirely functional, I think it's low risk in terms of data loss. I can't vouch for whether or not you know what you're doing.I've been having some chats with people lately about quoting posts, and honestly there has to be something better and straight forward. That continues to be a holy grail of mine, and some day, I hope to find it.Enjoy... it's starting to feel more real every day!

  • The Sitemap Paradox

    - by Jeff Atwood
    We use a sitemap on Stack Overflow, but I have mixed feelings about it. Web crawlers usually discover pages from links within the site and from other sites. Sitemaps supplement this data to allow crawlers that support Sitemaps to pick up all URLs in the Sitemap and learn about those URLs using the associated metadata. Using the Sitemap protocol does not guarantee that web pages are included in search engines, but provides hints for web crawlers to do a better job of crawling your site. Based on our two years' experience with sitemaps, there's something fundamentally paradoxical about the sitemap: Sitemaps are intended for sites that are hard to crawl properly. If Google can't successfully crawl your site to find a link, but is able to find it in the sitemap it gives the sitemap link no weight and will not index it! That's the sitemap paradox -- if your site isn't being properly crawled (for whatever reason), using a sitemap will not help you! Google goes out of their way to make no sitemap guarantees: "We cannot make any predictions or guarantees about when or if your URLs will be crawled or added to our index" citation "We don't guarantee that we'll crawl or index all of your URLs. For example, we won't crawl or index image URLs contained in your Sitemap." citation "submitting a Sitemap doesn't guarantee that all pages of your site will be crawled or included in our search results" citation Given that links found in sitemaps are merely recommendations, whereas links found on your own website proper are considered canonical ... it seems the only logical thing to do is avoid having a sitemap and make damn sure that Google and any other search engine can properly spider your site using the plain old standard web pages everyone else sees. By the time you have done that, and are getting spidered nice and thoroughly so Google can see that your own site links to these pages, and would be willing to crawl the links -- uh, why do we need a sitemap, again? The sitemap can be actively harmful, because it distracts you from ensuring that search engine spiders are able to successfully crawl your whole site. "Oh, it doesn't matter if the crawler can see it, we'll just slap those links in the sitemap!" Reality is quite the opposite in our experience. That seems more than a little ironic considering sitemaps were intended for sites that have a very deep collection of links or complex UI that may be hard to spider. In our experience, the sitemap does not help, because if Google can't find the link on your site proper, it won't index it from the sitemap anyway. We've seen this proven time and time again with Stack Overflow questions. Am I wrong? Do sitemaps make sense, and we're somehow just using them incorrectly?

  • How do you uninstall wine 1.5?

    - by jeff
    I installed Wine through the terminal using these commands: sudo add-apt-repository ppa:ubuntu-wine/ppa sudo apt-get update sudo apt-get install wine1.5 I know that I've removed at least part of wine. I removed the .wine folder in my home folder and I managed to remove the repository via this command: sudo apt-add-repository --remove ppa:ubuntu-wine/ppa Now when I try to install wine 1.4 via Ubuntu software center, it tells me I must remove these items to install wine: Microsoft windows compatibility layer (binary emulator and library) wine1.5 Microsoft windows compatibility layer (64-bit support) wine1.5-amd64 Microsoft windows compatibility layer (32-bit support) wine1.5-i386:i386 I've already tried this command: sudo apt-get --purge remove wine but it said that wine wasn't installed. Some assistance would be appreciated.

(tags: sun solaris virtualization) Mitch Denny: Architecture vs. Design It's an old post but it still resonates: "In the consumer electronics business, some people are actually hired to go through a system and remove components until it stops working – they do this to remove the cost before they go into mass production. We need more of this in the software business." -- Mitch Denny (tags: architecture design development) @vambenepe: Enterprise application integration patterns for IT management: a blast from the past or from the future? "In a recent blog post, Don Ferguson (CTO at CA) describes CA Catalyst, a major architectural overall which “applies enterprise application integration patterns to the problem of integrating IT management systems”. Reading this was fascinating to me. Not because the content was some kind of revelation, but exactly for the opposite reason. Because it is so familiar." -- William Vambenepe (tags: otn oracle eai)

  • The configuration section 'system.web.extensions' cannot be read because it is missing a section declaration

    - by Jeff Widmer
    After upgrading an ASP.NET application from .NET Framework 3.5 to .NET Framework 4.0 I ran into the following error message dialog when trying to view any of the modules in IIS on the server. What happened is during the upgrade, the web.config file was automatically converted for .NET Framework 4.0.  This left behind an empty system.web.extensions section: It was an easy fix to resolve, just remove the unused system.web.extensions section.   ERROR DIALOG TEXT: --------------------------- ASP --------------------------- There was an error while performing this operation. Details: Filename: \\?\web.config Line number: 171 Error: The configuration section 'system.web.extensions' cannot be read because it is missing a section declaration --------------------------- OK   ---------------------------

  • Is 4-5 years the “Midlife Crisis” for a programming career?

    - by Jeff
    I’ve been programming C# professionally for a bit over 4 years now. For the past 4 years I’ve worked for a few small/medium companies ranging from “web/ads agencies”, small industry specific software shops to a small startup. I've been mainly doing "business apps" that involves using high-level programming languages (garbage collected) and my overall experience was that all of the works I’ve done could have been more professional. A lot of the things were done incorrectly (in a rush) mainly due to cost factor that people always wanted something “now” and with the smallest amount of spendable money. I kept on thinking maybe if I could work for a bigger companies or a company that’s better suited for programmers, or somewhere that's got the money and time to really build something longer term and more maintainable I may have enjoyed more in my career. I’ve never had a “mentor” that guided me through my 4 years career. I am pretty much blog / google / self taught programmer other than my bachelor IT degree. I’ve also observed another issue that most so called “senior” programmer in “my working environment” are really not that senior skill wise. They are “senior” only because they’ve been a long time programmer, but the code they write or the decisions they make are absolutely rubbish! They don't want to learn, they don't want to be better they just want to get paid and do what they've told to do which make sense and most of us are like that. Maybe that’s why they are where they are now. But I don’t want to become like them I want to be better. I’ve run into a mental state that I no longer intend to be a programmer for my future career. I started to think maybe there are better things out there to work on. The more blogs I read, the more “best practices” I’ve tried the more I feel I am drifting away from “my reality”. But I am not a great programmer otherwise I don't think I am where I am now. I think 4-5 years is a stage that can be a step forward career wise or a step out of where you are. I just wanted to hear what other have to say about what I’ve mentioned above and whether you’ve experienced similar situation in your past programming career and how you dealt with it. Thanks.

  • Visual Studio confused when there are multiple system.web sections in your web.config

    - by Jeff Widmer
    I am trying to start debugging in Visual Studio for the website I am currently working on but Visual Studio is telling me that I have to enable debugging in the web.config to continue: But I clearly have debugging enabled: At first I chose the option to Modify the Web.config file to enable debugging but then I started receiving the following exception on my site: HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid. Config section 'system.web/compilation' already defined. Sections must only appear once per config file. See the help topic <location> for exceptions   So what is going on here?  I already have debug=”true”, Visual Studio tells me I do not, and then when I give Visual Studio permission to fix the problem, I get a configuration error. Eventually I tracked it down to having two <system.web> sections. I had defined customErrors higher in the web.config: And then had a second system.web section with compilation debug=”true” further down in the web.config.  This is valid in the web.config and my site was not complaining but I guess Visual Studio does not know how to handle it and sees the first system.web, does not see the debug=”true” and thinks your site is not set up for debugging. To fix this so that Visual Studio was not going to complain, I removed the duplicate system.web declaration and moved the customErrors statement down.

  • Dude, what’s up with POP Forums vNext?

    - by Jeff
    Yeah, it has been awhile. I posted v9.2 back in January, about five months ago. That’s a real change from the release pace I had there for awhile. Let me explain what’s going on. First off, in the interim, I re-launched CoasterBuzz, which required a lot of my attention for about two of those months. That’s a good thing though, because that site is just about the best test bed I could ask for. The other thing is that I committed to make the next version use ASP.NET MVC 4, which is now at the RC stage. I didn’t think much about when they’d hit their RTW point, but RC is good enough for me. To that end, there is enough change in the next version that I recently decided to make it a major version upgrade, and finish up the loose ends and science projects to make it whole. Here’s what’s in store… Mobile views: I sat on this or a long time. Originally, I was going to use jQuery Mobile, and waited and waited for a new release, but in the end, decided against using it. Sometimes buttons would unexplainably not work, I felt like I was fighting it at times, and the CSS just felt too heavy. I rolled my own mobile sugar at a fraction of the size, and I think you’ll find it easy to modify. And it’s Metro-y, of course! Re-do of background services: A number of things run in the background, and I did quite a bit of “reimagining” of that code. It’s the weirdness of running services in a Web site context, because so many folks can’t run a bona fide service on their host’s box. The biggest change here is that these service no longer start up by default. You’ll need to call a new method from global.asax called PopForumsActivation.StartServices(). This is also a precursor to running the app in a Web farm (new data layer and caching is the second part of that). I learned about this the hard way when I had three apps using the forum library code but only one was actually the forum. The services were all running three times as often with race conditions and hits on the same data. That was particularly bad for e-mail. CSS clean up: It’s still not ideal, but it’s getting better. That’s one of those things that comes with integrating to a real site… you discover all of the dumb things you did. The mobile CSS is particularly easier to live with. Bug fixes: There are a whole lot of them. Most were minor, but it’s feeling pretty solid now. So that’s where I am. I’m going to call it v10.0, and I’m going to really put forth some effort toward finishing the mobile experience and getting through the remaining bugs. The roadmap beyond that will likely not be feature oriented, but rather work on some other things, like making it run in Azure, perhaps using SQL CE, a better install experience, etc. As usual, I’ll post the latest here. Stay tuned!

  • Personal | Going For A Long Drive

    - by Jeff Julian
    This weekend, we were planning on going to Mt. Rushmore, but with the weather the way it is, we decided to head south instead. So what are we going to do? A tour of different restaurants on the show Diners, Drive-ins, and Dives. Not very original I know since there are web sites and iPhone apps dedicated to locating the establishments, but it definitely sounds like it could be some fun. We are going to leave KC tonight and go through St. Louis, Memphis, Little Rock, Dallas, Oklahoma City, and back to KC. The kiddos are excited and we have plenty of movies, coloring books, etc in the car for the trip. This will be the first time we will get to use our turn around seats in the mini-van with our pull out table. I will have my laptop and phone if anything goes wrong with the site while I am gone and John will be back in KC as well. I hope to pushing some photos and reviews of the restaurants as we travel.

  • Visual Studio Shortcut: Surround With

    - by Jeff Widmer
    I learned a new Visual Studio keyboard shortcut today that is really awesome; the “Surround With” shortcut.  You can trigger the Surround With context menu by pressing the Ctrl-K, Ctrl-S key combination when on a line of code. Ctrl-K, Ctrl-S means to hold down the Control key and then press K and then while still holding down the Control key press S. Here is where this comes in handy: You type a line of code and then realize you need to put it within an if statement block. So you type “if” and hit tab twice to insert the if statement code snippet.  Then you highlight the previous line of code that you typed, and then either drag and drop it into the if-then block or cut and paste it.  That is not too bad but it is a lot of extra key clicks and mouse moves. Now try the same with the Surround With keyboard shortcut.  Just highlight that line of code that you just typed and press Ctrl-K, Ctrl-S and choose the if statement code snippet, hit tab, and POW!... you are done!  No more code moving/indenting required. Here is what the Surround With context menu looks like: Just up or down arrow inside the drop down list to the code snippet that you want to surround your currently selected text with.  Did I mention this is AWESOME! Now it is so simple to surround lines of code with an if-then block or a try-catch-finally block... things that usually took several key clicks and maybe one or two mouse moves. And this works in both Visual Studio 2008 and Visual Studio 2010 which means it has been around for a long time and I never knew about it.   Technorati Tags: Visual Studio Keyboard Shortcut

  • The ugly evolution of running a background operation in the context of an ASP.NET app

    - by Jeff
    If you’re one of the two people who has followed my blog for many years, you know that I’ve been going at POP Forums now for over almost 15 years. Publishing it as an open source app has been a big help because it helps me understand how people want to use it, and having it translated to six languages is pretty sweet. Despite this warm and fuzzy group hug, there has been an ugly hack hiding in there for years. One of the things we find ourselves wanting to do is hide some kind of regular process inside of an ASP.NET application that runs periodically. The motivation for this has always been that a lot of people simply don’t have a choice, because they’re running the app on shared hosting, or don’t otherwise have access to a box that can run some kind of regular background service. In POP Forums, I “solved” this problem years ago by hiding some static timers in an HttpModule. Truthfully, this works well as long as you don’t run multiple instances of the app, which in the cloud world, is always a possibility. With the arrival of WebJobs in Azure, I’m going to solve this problem. This post isn’t about that. The other little hacky problem that I “solved” was spawning a background thread to queue emails to subscribed users of the forum. This evolved quite a bit over the years, starting with a long running page to mail users in real-time, when I had only a few hundred. By the time it got into the thousands, or tens of thousands, I needed a better way. What I did is launched a new thread that read all of the user data in, then wrote a queued email to the database (as in, the entire body of the email, every time), with the properly formatted opt-out link. It was super inefficient, but it worked. Then I moved my biggest site using it, CoasterBuzz, to an Azure Website, and it stopped working. So let’s start with the first stupid thing I was doing. The new thread was simply created with delegate code inline. As best I can tell, Azure Websites are more aggressive about garbage collection, because that thread didn’t queue even one message. When the calling server response went out of scope, so went the magic background thread. Duh, all I had to do was move the thread to a private static variable in the class. That’s the way I was able to keep stuff running from the HttpModule. (And yes, I know this is still prone to failure, particularly if the app recycles. For as infrequently as it’s used, I have not, however, experienced this.) It was still failing, but this time I wasn’t sure why. It would queue a few dozen messages, then die. Running in Azure, I had to turn on the application logging and FTP in to see what was going on. That led me to a helper method I was using as delegate to build the unsubscribe links. The idea here is that I didn’t want yet another config entry to describe the base URL, appended with the right path that would match the routing table. No, I wanted the app to figure it out for you, so I came up with this little thing: public static string FullUrlHelper(this Controller controller, string actionName, string controllerName, object routeValues = null) { var helper = new UrlHelper(controller.Request.RequestContext); var requestUrl = controller.Request.Url; if (requestUrl == null) return String.Empty; var url = requestUrl.Scheme + "://"; url += requestUrl.Host; url += (requestUrl.Port != 80 ? ":" + requestUrl.Port : ""); url += helper.Action(actionName, controllerName, routeValues); return url; } And yes, that should have been done with a string builder. This is useful for sending out the email verification messages, too. As clever as I thought I was with this, I was using a delegate in the admin controller to format these unsubscribe links for tens of thousands of users. I passed that delegate into a service class that did the email work: Func<User, string> unsubscribeLinkGenerator = user => this.FullUrlHelper("Unsubscribe", AccountController.Name, new { id = user.UserID, key = _profileService.GetUnsubscribeHash(user) }); _mailingListService.MailUsers(subject, body, htmlBody, unsubscribeLinkGenerator); Cool, right? Actually, not so much. If you look back at the helper, this delegate then will depend on the controller context to learn the routing and format for the URL. As you might have guessed, those things were turning null after a few dozen formatted links, when the original request to the admin controller went away. That this wasn’t already happening on my dedicated server is surprising, but again, I understand why the Azure environment might be eager to reclaim a thread after servicing the request. It’s already inefficient that I’m building the entire email for every user, but going back to check the routing table for the right link every time isn’t a win either. I put together a little hack to look up one generic URL, and use that as the basis for a string format. If you’re wondering why I didn’t just use the curly braces up front, it’s because they get URL formatted: var baseString = this.FullUrlHelper("Unsubscribe", AccountController.Name, new { id = "--id--", key = "--key--" }); baseString = baseString.Replace("--id--", "{0}").Replace("--key--", "{1}"); Func unsubscribeLinkGenerator = user => String.Format(baseString, user.UserID, _profileService.GetUnsubscribeHash(user)); _mailingListService.MailUsers(subject, body, htmlBody, unsubscribeLinkGenerator); And wouldn’t you know it, the new solution works just fine. It’s still kind of hacky and inefficient, but it will work until this somehow breaks too.

  • A debugging experience with "highly compatible" ASP.NET 4.5

    - by Jeff
    I have to admit that I will pretty much upgrade software for no reason other than being on the latest version. I won't do it if it's super expensive (Adobe gets money from me about once every three or four years at best), but particularly with frameworks and stuff generally available as part of my MSDN subscription, I'll be bleeding edge. CoasterBuzz was running on the MVC 4 framework pretty much as soon as they did a "go live" license for it. I didn't really jump in head-first with Windows 8 and Visual Studio 2012, in part because I just wasn't interested in doing the reinstalls for each new version. Turns out there weren't that many revisions anyway. But when the final versions were released a week and a half ago, I jumped in. I saw on one of the Microsoft sites that .Net 4.5 was a "highly compatible in-place update" to the framework. Good enough for me. I was obviously running it by default in Windows 8, and installed it on my production server. I suppose it's "highly compatible," except when it isn't. Three of my sites are running with various flavors of the MVC version of POP Forums. All of them stopped working under ASP.NET 4.5. It was not immediately obvious what the problem might be beyond an exception indicating that there were no repository classes registered with Ninject, which I use for dependency injection in the forums. This was made all the more weird by the fact that it ran fine locally in the dev Web host. My first instinct was to spin up a Windows Server VM on my local box and put the remote debugger on it. (Side note: running multiple VM's on a Retina MacBook Pro with 16 gigs of RAM is pretty much the most awesome thing ever. I can't believe this computer is for real, and not a 50-pound tower under my desk.) What might have been going on in IIS that doesn't happen in Visual Studio? In the debugging process, I realized that I might be looking in the wrong place. POP Forums creates a Ninject container using a method called from a PreApplicationStartMethod attribute, and at that time registers a module (what Ninject uses to map interfaces to implementations) that maps all of the core dependencies. It also creates an instance of an HttpModule that originally hosted the "services" (search indexing, mailer, etc.), but now just records errors. That's all well and good, but the actual repository mapping, where data is actually read or persisted, happens in Application_Start() in global.asax. The idea there is that you can swap out the SqlSingleWebServer repos for something tuned for multiple servers, Oracle or something else. Of course, if I used something like StructureMap, which does convention-based mapping for dependency injection (a class implementing ISettingsRepository called SettingsRepository is automagically mapped), I wouldn't have to worry about it. In any case, the HttpModule, being instantiated before Application_Start() gets to run, would throw because there was no repo mapped where it could get settings from the database. This makes total sense. The fix is sort of a hack, where I don't setup the innards of the HttpModule until a call to its BeginRequest is made. I say it's a hack, because its primary function, logging exceptions, won't work until the app has warmed up. Still, this brings up an interesting question about the race condition, and what changed in 4.5 when it's running in IIS. In ASP.NET 4, it would appear that the code called via the PreApplicationStartMethod was either failing silently, and running again later, or it was getting to that code after Application_Start was called. In any case, weird thing. The real pain point I'm experiencing now is a bug in MVC 4 that is extremely serious because it renders the mobile/alternate view functionality very much broken.

  • .NET development on a “Retina” MacBook Pro

    - by Jeff
    The rumor that Apple would release a super high resolution version of its 15” laptop has been around for quite awhile, and one I watched closely. After more than three years with a 17” MacBook Pro, and all of the screen real estate it offered, I was ready to replace it with something much lighter. It was a fantastic machine, still doing 6 or 7 hours after 460 charge cycles, but I wanted lighter and faster. With the SSD I put in it, I was able to sell it for $750. The appeal of higher resolution goes way back, when I would plug into a projector and scale up. Consolas, as it turns out, is a nice looking font for code when it’s bigger. While I have mostly indifference for iOS, I have to admit that a higher dot pitch on the iPhone and iPad is pretty to look at. So I ordered the new 15” “Retina” model as soon as the Apple Store went live with it, and got it seven days later. I’ve been primarily using Parallels as my VM of choice from OS X for about five years. They recently put out an update for compatibility with the display, though I’m not entirely sure what that means. I figured there would have to be some messing around to get the VM to look right. The combination that seems to work best is this: Set the display in OS X to “more room,” which is roughly the equivalent of the 1920x1200 that my 17” did. It’s not as stunning as the text at the default 1440x900 equivalent (in OS X), but it’s still quite readable. Parallels still doesn’t entirely know what to do with the high resolution, though what it should do is somehow treat it as native. That flaw aside, I set the Windows 7 scaling to 125%, and it generally looks pretty good. It’s not really taking advantage of the display for sharpness, but hopefully that’s something that Parallels will figure out. Screen tweaking aside, I got the base model with 16 gigs of RAM, so I give the VM 8. I can boot a Windows 7 VM in 9 seconds. Nine seconds! The Windows Experience Index scores are all 7 and above, except for graphics, which are both at 6. Again, that’s in a VM. It’s hard to believe there’s something so fast in a little slim package like that. Hopefully this one gets me at least three years, like the last one.

  • AJI Report with Nat Ryan&ndash;Discussion about Game Development with Corona Labs SDK

    - by Jeff Julian
    We sat down with Nat Ryan of Fully Croisened to talk about Game Development and the Corona Labs framework. The Corona SDK is a platform that allows you to write mobile games or applications using the Lua language and deploy to the iOS and Android platforms. One of the great features of Corona is the compilation output is a native application and not a hybrid application. Corona is very centered around their developer community and there are quite a few local meetups focused on the helping other developers use the platform. The community and Corona site offers a great number of resources and samples that will help you get started in a matter of a few days. If you are into Game Development and want to move towards mobile, or a business developer looking to turn your craft back into a hobby, check out this recording and Corona Labs to get started.   Download the Podcast   Site: AJI Report – @AJISoftware Site: Fully Croisened Twitter: @FullyCroisened Site: Corona Labs

  • Personal | First Stop on our trip, St. Louis

    - by Jeff Julian
    St. Louis is definitely a cool city. I have always looked at it as Kansas City’s big brother. I love to Arch, wonder what is would be like to have pro hockey, really like the downtown area, and have some great friends who live there. The reason we left for St. Louis on Thursday evening was to get us a head start on our journey. Since we were doing a Diners, Drive-ins, and Dives tour, it made since to have the journey start there. We picked the Hyatt Downtown as our hotel because they had an Arch Package which was suppose to get you tickets to the arch so you didn’t need to arrive early and wait in line. That ended up not working cause the arch had been selling out every day and they were no longer accepting the hotels tickets. No biggie and the hotel did try very hard to get us tickets, but we just took our chances in the line and waited. We walked over to the park and had to wait for about 20 minutes for the doors to open and had tickets after another 20 minutes of waiting in line and at that point walked right up and were able to get to the elevators.I want to stop here to have a little aside. I don’t know who started the rumor that the arch ride is scary but it is not. You do sit in a small pod, but it like the accent on a roller coaster to the top of the first drop and an elevator with no windows outside. Nothing to be afraid of here if you aren’t claustrophobic. If you are afraid of small spaces, stay clear of this ride. Once you get to the top, you walk up 10 to 30 stairs depending on which car you were in (lower the number the less stairs you climb) and you are then at the top in a decent sized room where you look out the windows. Beautiful view of the city. I don’t typically like heights, but this felt like being inside a building and not hang out on a roof. Here is the view from the arch: Related Tags: Diners, Drive-ins, and Dives, St. Louis, Vacation
