I know a man that has a small RV park just outside Greensboro. And a man that has a new RV park with lots available near Demopolis. I think it's near Gallion on hwy 80 east of town. I can put you in touch with either one if your interested.
You mentioned duck hunting. My son has traveled many states after ducks. He also hunts the sound sometimes.
Let me know when your coming up and we'll plan to have lunch together.
