This is a video of Craig Benzine involved in some "parkour for the common man." It's basically parkour without any impressive tricks or stunts (although I did find the "self-dodger" move at 1:20 pretty slick). So, what do you say -- meet at the middle school after work and do some parkour? "I'll pass." Cool, I was just going to stand you up anyways.
Keep going for the video. Then get out there and twist some ankles!
Thanks Craig, now how about some bad rollerblading to wash this down with?
