I have a great memory of Custer State Park. In 1972 I was a community organizer in a Lakota Sioux community. Several of us took a break and were driving through the park when we we ended up in the middle of a bison herd of several hundred animals. A woman from Chicago in the back seat became frightened and began screaming. Let's just say that the unwanted attention was not a good thing. I was driving a 1963 Volvo 544 (peanut sized) and several males brushed up against the vehicle. My yelling at her was also not a good thing. It was a memorable event.
