Rinky-dink is a good description. I believe what is now a maintenance shed was the museum. All I remember about it is the human skeleton they had on display. The area was also very heavily-wooded at the time and, as I mentioned, was more of a state park than a historic site, with picnics and other recreation going on. I’m surprised some of the smaller mounds weren’t seriously damaged, because kids played on them and people evidently sat on them to get a free view of the old Falcon Drive-In Theater that used to stand at the edge of the site.
