East coast trip heading south

I have beat that route to death but stayed out of NYC and Boston. Cherry Hill is good, stayed there first time in 1970 or so. If that is packed there is a KOA in Millersville, MD. With a truck camper you can park at BWI Amtrack station and ride to DC on the train--pretty easy. Annapolis, MD. 911 memorial in PA, Que Creek mine memorial, Gettysburg, Hersey, Harpers Ferry, WV, Winchester, VA. This post would be to long if I continue as we spent the last 2 years from PA to Palm Beach and stopped everywhere in between. I lived in DC years ago and never saw anything till relatives came to visit. Take a long time to see it all.
