Ok so I've been watching parkour bails (fun stuff, because I enjoy participating in parkour too!) and usually i would comment but i wanted to say some things important for young people getting into parkour:
1) Don't over try, always start easy. Looks like some of the guys in this are trying too hard.
2) While many of them did bail painfully, it looked like a lot of them also managed to recover as well. Doing it perfectly isn't as important as satying safe, so good job!
Have some fun!
