At the time of my completing the quiz, 21% said riding a skateboard in the park violated the rule. But only 13% said carrying a skateboard violated the rule. I'm puzzled by that. Does a vehicle stop being a vehicle when it's not vehicularizing? It'd get it if it were, "Jane carries a food tray" versus "Joe rides a food tray down the hill." But here the skateboard's purpose is to be ridden.
