     I BMXed from 1978 (my first race) till not too long ago. Although I don't see too many freestylers in the net, I get in touch with quite a few ex-BMXers like myself on rec.bicycles.off-road (I'm cross-posting to it).

     Yeah, flippity trick things are fun. I've got a friend who has BMXed for 15-16 years! He rules, and he used to be sponsored.
