This is an amazing spot. If you're lucky, you'll get a site right on the Tom Bigbee waterway under the shade of pines and hardwoods. At first I was taken aback by the Mississippi culture; apprehensive at first but kind and welcoming. This place is great for a holiday weekend -- it's packed with campers outdoing one another with the lights at night around their sites. Kids on bikes are everywhere and everyone is friendly. All for $22 a night.
While you're here, make sure you visit some of the local towns (like Aberdeen and Columbus) to get a flavor of the area. Also, there's a great local restaurant called Friendship House that serves steaks and seafood (catfish and shrimp).
