Which states qualify as culturally Southern?

[Donerail]

Florida outside of Miami is definitively the South.

Aye.  I lived in Panama City (Tyndall AFB) for 2 years and it's quite rednecky.  Especially if you dare to drive inland for about 10 minutes.  Where I was at wasn't too bad because of the AFB and the "party" culture of PCB, but head north and it turned Deliverance right quick.

I spent the night in Quincy, Florida. It's right on the Alabama border and I had to remind myself several times that I wasn't in Alabama .

I'd expand the Miami qualification all the way up to Orlando, minus the Everglades/central southwest Florida areas.

The line between 'South' and 'not-South' is very much an iffy line. Glades are definitely Southern, but Naples isn't. La Belle is, but Cape Coral isn't. Hell, Ocala is, but Gainesville really isn't. There's really no way to draw the line clearly, but I-4's probably the best line that exists.
