Skateboarding

I found out yesterday that it is illegal to do skateboard tricks on campus. A friend of mine was threatened to get SNAM'ed if he didn't stop showing us how much better he had gotten immediately. The officer proceeded to tell us that it is legal to ride your skateboard as a transportation device but not to do tricks do to the fact that if you were hurt doing tricks on campus you could sue the school. I wonder if you could also sue the school if you were just riding your skateboard around and was injured. I could use some extra money...
