I should have mentioned we like secluded RV parks with lots of trees and quiet surroundings. Don't need any amenities except do enjoy full hook ups. Somewhere you could sit outside and enjoy a cigar and a glass of whiskey at the end of the day without having visitors. We aren't prepared to boondock in the wilderness yet but do like that kind of privacy if that makes sense. This is our down time.
