Skateboarding is a true art form. It represents the tension between practice and art that becomes a balanced freedom. I never learned how to skateboard, but I always admired it as a sport. Many people become very angry at skateboarding, and that is another reason why I think it is so artistic. Strong visceral responses identify good art. I judge a neighborhood by the quality of it's skatepark.
PS. Please protect your greatest asset. Always wear a helmet when riding! Now, as I say in my Art-o-Mat column, "Find a skateboard. Lose a collar!"
