Go west. Pa has some nice state parks,most have electric hookups.One, Promised Land's Pickeral Point Campground has a loop with full hookups and brand new bath houses.It's not far from Jersey. Take I-80 west. We also enjoy Locust Lake and Pine Grove Furnace.Both can be accessed from I-81 south. Both have swimming beaches. Locust Lake has a paved trail around the lake for bikes or walking. Pine Grove Furnace has new bath houses,a new snack bar bath house at the lake,a small visitor center and,if you like history,a former POW camp close by. They have have a pamphlet for a self guided tour and sell a book on it.If you have a dog,make sure you get a pet site.
