An interesting idea, though I have the problem of being in a rural area in Western NC. Thus, my experience with the site is going to be limited. However, the next county over is Asheville, which would have a greater chance of meeting up with people who have similar interest. I know you can search by metro area in the search, but it'd be nice to be able to add additional counties or nearby areas for the username, either automatically (If the user wants it) or manually.

This was also be of help to people who travel from one area or another a lot (I go to Knoxville several times a month, for instance.)

But so far, I like the idea and I'm interested in seeing how it grows.
