depends on what you want to do, how big of a hurry
McComb (MCB) Mississippi might be of some interest. We stopped up for a lunch one time and enjoyed the Dinnerbell resturant. Believe they only serve lunch during the week with "open seating". They have a web site. Fine southern cooking, and you eat with a dozen or so other folks at a huge round table with lazy susan. We used the crew car from the airport. also close by is state park with lake, golf course and "hotel",... bit of state park flavor,.. not a 5 star type hotel. In town is a small museum to the railroad, they used to have a major maintenance/modernization facility in town. They have one of the largest steam engines on display.
Further west is Lost River (HZR) Enterprise car rental will come and pick you up during week, and on Sat morning. For local flavor, and just across the river, is St Francisville, a nice tourist town for old south flavor. (used to have to take a ferry ride, believe the new bridge is open now)
Of course you could stop at Pensacola and go to the Naval Aviation Museum, and short hop over to Mobile Downtown,... can get on the old battleship Alabama, and tour the ship including turret and engineroom.
