Man, the whitewater sports are awesome. Watching these athletes, the only thing I can think is "No way I could ever do that well." It requires strength, quickness, balance, good vision, quick thinking and probably a bunch of other things I'm not thinking of. And oh, yeah: Not getting fazed by swallowing about a gallon of water as you get dumped on.
Mad props to the whitewater fiends. Really the bomb for this city slicker.
