We camped at Shenango Recreation Area in late September. Arriving on a Wednesday and planning on departing on Sunday, we weren’t even sure they were open when we arrived. No one was at the gate and after some fumbling around, we realized that it was the honor system until the weekend. We drove around and chose our spot (much of the park was closed and unavailable), then headed back to pay by sticking a check in an envelope and placing it in a lock box. The ranger did stop by later and check our site and the campground hosts were still there, so all was good.
