Our family of 5 got sick 4 years ago in Grayton Beach in June. Diarrhea and vomiting from e-coli in the water. Even if you step on the wet sand, you can be infected. Spoke to some other people in the area and same thing. No warnings. No signs. Vendors, etc. were trying to keep it hush hush. Didn't want it to affect tourism. Won't go back again.
