In the keys there is a park called LONG KEY STATE PARK. They charge 40$/night to camp with water and electricity but you can also camp out in an area on the beach without water and electricity and its only $8/day. I feel your pain. From West Palm Beach county to Key West everything is restricted heavily. There are curfews in effect. Camping on the beach is a definite police magnet. Its a shame but they don't allow that kind of stuff here. Now its becoming more common also that in order to just kitesurf you need to pay for certification.
