We are camping in Conway, NH, at Green Meadows Campground, located in the White Mountains. This park is typical of the parks in the area, and is, I guess, 60% seasonal campers. This weekend, the row we are in which has 10 sites, had 4 sites occupied. Three of those left on Sunday, and the fourth left yesterday. We are now the only camper in our row. 90% of the seasonal campers left. We did a road trip to Stowe yesterday, passing several parks, and most were sparsely occupied. It's not just RV parks; the motels and hotel parking lots are practically empty.
We drove through two National Forest campgrounds yesterday, and once again, out of 75-100 sites, they had maybe 10 campers. We talked to one host, and he said they are about 75% full on the weekends.
As a side note, the last park we stayed in, according to their online reservations, they only had 4 sites available, and this was a park with over 200 sites. We reserved one site, arriving on Thursday and leaving on Sunday. The park must have had 100 unoccupied sites the whole time we were there. My thought was that the software programs are playing some games, causing us to believe we'd better grab a site when we can.
