Don't Approach the Bison in Yellowstone National Park

Occurred on July 31, 2018 / Yellowstone National Park, Wyoming, USA

Info from Licensor: "My family and I were driving through Hayden Valley in Yellowstone looking at wildlife and the scenery when we noticed that the traffic had slowed due to bison along the road. I videoed him from our vehicle as he was walking and making growling sounds. We noticed behind us, a man in socks and no shoes walking up the road towards the bison. He gestured to the animal to get off the road and then proceeded to challenge him. The bison went after him a couple times and then carried on with what he was doing before he was bothered. The man did not appear to be injured and we are unsure of what happened to him after as we moved forward with traffic."
