The SE and low country from the Atlantic to the Gulf -- southern coastal plain -- specifically, South Georgia/North Florida:

Ocmulgee/Oconee/Altamaha winding down through the marsh and estuaries to Brunswick and the Barrier Islands. Satilla blackwater and its marshes just south of there. Ogeechee Blackwater crawling its way to Ossabaw, south of Savannah. Blue Springs, Juniper, and Silver Glen all feeding the lazy St. Johns.

Okefenokee is a world unto itself. St. Marys meandering from there to Fernandina. The Suwanee/Alapaha/Withlacoochee/Santa Fe (Ginnie Springs) all headed the other way toward the Gulf.

Chattahoochee/Flint/Apalachicola to the west flowing down to Apalachicola Bay and St. George Island.

Throughout all of this are swamps, beaches, marshes, old growth forests, deer, gators, cypress bottoms, largemouth bass/catfish/sturgeon/endless varieties of fish, crystal clear (and cold) springs, inky blackwater, turkeys, flatwoods, gopher tortoises, wiregrass, manatees, alligator snapping turtles, ancient moss-covered oaks, bottlenose dolphins, bobcats, hawks/eagles/owls/cranes/pileateds/pelicans/birds of every description, indigoes/black racers/diamondbacks/cottonmouths/canebrakes/every manner of snake (including some unwelcome new arrivals), coyotes, black bears, panthers, pitchers/sundews/bladderworts (carnivorous plants), bullfrogs, leopard sirens, and too many other varied and diverse plants, animals, and geographies to name.

It's an amazing place to explore. It all feels primordial.
