Well, your second guess was close, it is actually the Tallahassee Fl area. Anywhere on US 98 from Perry Fl to Apalachicola and Mexico Beach, Fl , all that is the Redneck Reviera.  This includes St George island, Ile De-shiene ( Dog Island ) etc , along the coastal route. Known as the Big Bend Area of North Fl.

If you've never been down here you sure are missing lots of 'smoked mullet', oysters on the half shell, uncrowded beaches  etc. If you listen to country music, well, Tom T Hall has an entire album about this area, 'Redneck Reviera'. You can download one mp3 titled "Lost in Florida"  as a sample. And I have a cabin on the beautiful, pristene, unpolluted Sopchoppy River that I dearly love spending time at.
So now you know.
