Did you notice that when maps.google.com cannot find your location, it always displays the same map? It's somewhere in Kansas, close to the Oklahoma border:

It made me think of The Wizard of Oz, so I searched where Dorothy Gale was from. She's from Liberal, Kansas, which is way to the West of what's displayed.

The first thing you notice is the Coffeyville Country Club. So I've googled for "Coffeyville Country Club Google", and realized this was simply the default location when you open maps.google.com, and zoom in... Google Maps' center of the United-States... Dah! So much trouble for a so simple solution.
