After reading this post I went to Wikipedia to find out just where the "Deep South" is. Seems it includes East TX, LA, MS. AL,GA & West FL. Since the OP indicated an interest in the Gulf Coast, this narrows the search somewhat. I would recommend getting on US 90 somewhere in East TX and travel east. Switch to US 98 once in a while to stay on the coast. Visit all the National Seashores, national wildlife refuges, old Forts, and quaint towns along the way. Visit barrier islands, climb lighthouses. Camp in state parks, national forests, and other out-of-the-way places. Ask the locals where to eat, especially seafood. When you get to the Suwannee River stop and take stock. The "deep" Gulf South is over. Lots of "Old South" to see but it is to the north of you now. lizzie
