Steel,
I just registered for this Web site a few days ago, although I've had my eye on free running for a couple of years.
I live in Columbia and am a junior at Mizzou. I've never really trained for free running/parkour but I've always been really interested in it. If your brother is looking for another amateur to start training with, we could possibly start together.
Considering Columbia is a big college town with three colleges and numerous high/middle/elementary schools, I've always thought it to be an excellent place for free running - not to mention the Mizzou Rec Center - which is without a doubt the perfect gym to train in. Quite frankly, I'm actually surprised to see no one else at Mizzou really does free running (unless there's some kind of secret society of it, haha) because the community in Columbia is extremely diverse and open.
I am pretty busy but if I had someone to keep me motivated, I'd definitely give training for free running an important amount of time.
