I think this thread should even be made sticky! basically, there's this site, with a map, and you put in your location, and you can see the locations of other people (not their address or anything, but city and state) and stuff like that. I started one for guitartricks, and right now I'm the only member, so you can go sign up and you can see where other GT members reside in relation to you!
