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!
that should be the right link, I'm not 100% though. go join!
