Day before yesterday I was sitting outside a restaurant having dinner, and a guy was riding his skateboard down 1st street. Two things struck me. First, it was rush hour, and I gotta believe that a skateboard is more sensitive to gutter-crap than a bike so he must have been a good distance from the curb. Even so,it's a pretty crappy road regardless. Second, while he was working his right leg like I'd never seen anyone do, and was moving at a pretty good clip for the 50 feet after every push, he must have felt a bit slow. Might have explained his rather frenetic pace & expression ;-)
Still, I was impressed. I don't think I'm going to go get a board, but this guy seemed to have it down to more of an art form than most. He had to be using it for transportation. If he was on that street for fun, well, he needs to try another street. Almost any street.
