You fellers best do a Google on Deer Island and at least know what to expect when someone with a badge shows up and starts asking y'all questions. That was just to get your attention, but in all seriousness, a quick Google I did turned up some interesting facts. First one was that the island has been designated as a Mississippi Coastal Preserve, and you can bet there will be at least another half dozen designations right in there with that one.All Big Brother, Little sister(you know what she can be) You know what that means, permits, license, permission(Fees) for "whatever" you are doing there and if they (dude with the badge)don't have a category to fit you in they will use the Antiquities Act,, and that will smoke your butts!. Just be cool and check it out before you cause yourself some real grief. You might can even get permits and detect legal, buy I would not get my hopes up.
