Ive had the DPD tell me that it is illegal to swim in any part of Detroit except for Belle Isle Beach. I would like to look up how this works. B.I. has many small swim holes but its not until someone drowns that the Police will start writing tickets or at least start writing MORE tickets than normal. Im having a hard time believing that there is a law forbidding swimming anywhere but the B.I. Beach. Do they even have lifeguards there?
