A smallish (35 sites w/hookups) county campground next to Lake Ontario opened here in upstate NY last week, self contained only. I took the 10 mile ride to check on it and there were port-a-potties next to the bathrooms. So I am not sure how self contained you have to be. No restrictions on PUP's that I am aware of. Looking to get there in June. No word on state park campgrounds, although beaches at state parks are supposed to open mid-June, maybe campgrounds aren't far behind.
