Hi, I am picking my son up from college and would like to plan a little sight seeing on the way home. We will be traveling from his school in Houston,Tx and driving back to Sevierville, Tn. It is such a long trip and it would be nice if I could find some somewhere to stop for a day to sight see or attractions near the road where we can stop and look and jump back on the road. I dont know where to begin. We will have 2 days to wander. Also, what would be a good scenic route to drive. Any help would be greatly appreciated.
