I've read the chat about it. I personaly dont know. Some of these guys fish a lot at night and are very protective of there spots. It may be a way to keep others away?
Just dont wade over your ankles and you should be o.k. On second thought, last year a shark was seen beaching itself going after a seal pup on South Beach.
Are you allowed to carry shot guns on S. Monomoy? while fishing?
