There are some underwater caves in the Gulf of Mexico around Weeki Wachee.
St pete is pretty close to being at sea level most houses in the area don t even have basements because of the water table. If you don t believe me just go outside and dig a hole in the sand and stop when you hit water. Won t take long.
