I evidently chose the one site that has no daytime shade. There was shade early and late, but nothing in the middle of the day. Crews were pruning a lot of dead branches in the park as well. Access to water was not convenient unless you drove.
Most campers showed up in the evening. Campground was about 75% full by nightfall. Just up the road in Lewis and Clark SP. I drove through and it was pretty full. All sites are electric. Fairly close together. Free showers were great to rinse off sweat from heat and humidity. Oh yes - Fireflies!!
