We're currently in a NY state park campground that was 100% booked except for some of the primitive tent sites in the weeks leading up to Labor Day. As of Tuesday afternoon, the park was down to about 15% occupancy, and about 10% today. As already said, most of our reservations for this winter in Florida, where we mostly hop from state park to state park, were made before we left last winter. Even then we were unable to get into a couple of our first choice parks at 8am on the day the 11 month advanced reservation windows opened at Reserve America. Fortunately, we were able to fill those gaps later on when the 6 month window opened for the national parks. "It's a jungle out there!"... ;)
