title: How is this particular site finding my location? http://freebirds.com/locations/
body: <p>IP geolocation always seems to get me wrong (it returns the town my ISP is based in, which is 180 miles east of here), so I am wondering what they are using. However, I couldn't tell by looking at their source. Did I miss it or are they doing something server-side?</p>
  
  <p>I'm using a desktop browser. I tried it in Chrome 17 and IE 7 and it worked in both apps.</p>
