When I was preparing to drive out of the parking area after a short backpacking trip in Wind Cave National Park, 2 bull bison were grazing in a direction which would take them across my road - close. I decided to just wait for them to graze across the road. It gave me about 30 minutes of being able to watch them pretty close, with no danger.
When I was in my tent, I heard strange sounds on 3 side all night. I couldn't figure out what animal was making the sounds. In the morning, I saw that the sounds had been made by bison bulls. It was mating season. I had not been in any danger from them.
These weren't the only times I've been on the same side of the fence as bison. You have to learn how to behave around them, with respect above all.
