My wife, 2 year old daughter and I will be making a road trip the 2nd week of July. We will be traveling from Frederick, MD, Argillite , KY. The planned route is route 68 to route 79. Anyone have any recommendations on places to stop and see along the way. It's about a 6 1/2 hour drive so I'm trying to find some things to stop and do along the way to breakup the day of driving.
