The first gaming group that I got involved with as a kid rented the community center of a local bank to use as a gaming area. And there's a group active right now which holds monthly wargaming sessions in the community room at the local mall. If there's a conveniently located college nearby, that might work out, as well, as a source of gaming room.
Make up a group, advertise online and see if you can put of fliers at the local comic book shops, the library, that not-so-local gaming store, etc.
