We have a 35' RV and are looking for 4/5 star RV parks in Pennsylvania. We are not familiar with the State so are up for suggestions. We like to stay busy and see things while camping but also like activities on the campground -we would be traveling this summer from Mass. None of us have children - are in our 50's and have 5 RV's traveling together. Any suggesions where to stay or things to see while there would be appreciated.
