Parkour being the stuff without flips n shizzle, though I might learn that at some stage.
I've sort of taken it upon myself to spend some of my time - hopefully some time out with friends every week - learning parkour. We went out last Thursday, and tested the waters (3 of us). I'm fairly happy with my current abilities - I can do basic landings and rolls (rolls on grass for now), I can tac up a small wall, I can do basic vaults, and I can climb walls to some extent.
Does anyone else do parkour? Has anyone got any tips? I'd like to get through as much as I can, though I live in the middle of nowhere so meet-ups once or twice a week are the only time I really have to learn the majority of things.
