No Snowballs at Trees

In Bensalem Township, Pennsylvania, it is unlawful to throw a snowball at a tree. Huh????

The actual language of Code Section 160-1, Prohibited Acts, states: "(8) To throw any stone, snowball or any other object upon or at any vehicle, building, tree or other public or private property . . ."

Maybe Bensalem has unusually hard snow . . .
