I don't get why it'd doing this with the 2nd feed (appearing as a XHR call rather than just JS [looking at it in Firefox/Firebug]). The 2nd feed has the exact same MIME type as Flickr's JSON feed, yet the PortlandOregon.gov one shows as XHR and i get a NULL callback when using $.getJSON and if i use $.ajax with a 'json' or 'jsonp' type i get nothing at all. If i do the Flickr one i get the normal "[object Object]" callback.

Whats going on? Please help! This has been such a headache for about a week. And i have authorization to change the feed, but i have to request the change, so if anyone knows for absolute sure let me know that!
