Does the kitty in the harness go along?
We take our 2 in the camper and they love going "walkies" around campgrounds! Looking at everything and teasing the doggies LOL
Loveless Cafe at the end of the Trace when you get to Nashville is yummy! And if you like country music the Grand Ole Opry is always a good show. And I like this quilt shop:

Oh, allow plenty of time to stop at all the sights along the Trace. Be sure to walk on a portion of the old Trace - it gives me the chills to think of how many walked that route!
