we were camp hosts at Chadron State Park in NE for about 4 years and enjoyed every day of it. There were very few problems with people there. Once, a group of girls from the local college came up to camp and of course, some college boys came up to visit and they got a bit loud late that evening, so DH had to go run them off (nicely). The last year, we had to evacuate the park because a forest fire was threatening. Luckily the fire fighters kept the park from burning, but it burned all around it.
It's a nice park, well run.
