We also went out to Mud Island on the Mississippi. They have built a scaled model of the river showing which states it passes through, the cities on the river, and the depth of the river along the way.It was really cool! You could walk through the "Mississippi!" And it was neat to see the different cities along the river as it flowed through different states.
This is one of the beginnings of the Miss. If you look closely you can see a little dam in front.
So that was another educational part of our vacation. =)
All in all we recommend Memphis for a weekend vacation. Let us know if you decide to go, we just might come along! =)
