Most beaches have "stay off the dunes" signs, but not North Cape

North Cape May - Most beaches have "stay off the dunes" signs, but not North Cape May. Believe me, I am not advocating for more signage on the beach! I know people are allowed to cross the dunes using the designated pathways, but are kids allowed to play/dig/slide on them? It's a frequent sight, but not one I think is helpful to our dunes.
