We are a well travelled English couple in our 60's. We have driven all over the USA but not yet into this area of the south. We should welcome any suggestions as to how much time to spend on the Parkway - I know it is a slow drive (it is a scenic route after all!) We have about 15 days or so to do this journey and spend a little time in each of the stopovers so any thoughts on what is best to see en route would be helpful. We know about what to see and do in Nashville and Memphis and have been in Washington DC several times before. I am no longer a hiker sadly but we are very interested in history and the wonderful scenery to be found and photographed.
Many thanks for any suggestions.
