"New Jersey is becoming the 14th state to allow crossbows in all its archery seasons, and New York and Pennsylvania are considering it. Only three states do not allow them at all. In at least one state, Massachusetts, it remains illegal to even own a crossbow."

It doesn't list what other 2 states are illegal to even own one, but I do not believe it is NY.
