I tried to do a kickflip once. I was probably fourteen or fifteen. My form was pretty good, I'd like to think. I kicked. I flipped. But somehow the board ended up - in mid-air, mind you - to orient itself in a vertical position. I came down onto it hard right between my legs.
Waldo suffers no such grievous injury in this video. I will admit, though, that before he brought out his skateboard I said, "If you wipe out, I'll probably be really happy."
I tried to capture the feeling of skateboarding here. It's a bit like golf, I suppose. Lots of failure and frustration until that one perfect moment when you execute flawlessly.
