One of the good places that I have been has been recently is Indian Creek in Utah. There were a lot of folks living in vans in dispersed camping, just hanging out and climbing. I found it very easy to meet folks in that community. Specifically, I've found it easy to just walk up to a camp fire and introduce myself. Lots of folks are looking for partners to climb with. I love to climb, but there is definitely a side-benefit of being able to meet a bunch of people who have motivations to do similar things, and climbing lends itself well to dirt-bagging. I can't comment on other subcultures or sports. My experiences with musicians has been similar, though.
