It's on a little island in the middle of the Mississippi River, and is called "Mud Island Park." It's full of biking trails and such, but we spent our time playing in a scale model of the Mississippi River. It's very detailed, including elevations, cities, bridges, dams, flood areas, spillways, and where the rivers that feed the Mississippi come from. At the end of the river, in New Orleans, is the delta area, a fountain, and a pond where you can rent paddle boats. It was the perfect way to cool off after a long, hot and humid day! So, next time your in Memphis, make this a planned stop!
