On my web site, I'm trying to accomplishes the fastest page load as possible.

I've noticed that it appears my JavaScript are not loading asynchronously. Picture linked below.

How my web site works is that it needs to load two external JavaScript files:

Google Maps v3 JavaScript, and
JQuery JavaScript

Once it loads these external javascript files, it then, and only then, can dynamically render the page. The reason why my page can't load until both Google Maps and JQuery are loaded is that - my page, based on the geolocation (using Gmaps) of the user will then display the page based on where they are located (e.g. New York, San Francisco, etc). Meaning, two people in different cities viewing my site will see different frontpages.

Question: How can I get my JavaScript files to download asynchronously so that my overall page load time is quicker?
