Occurred on August 20, 2023 / Yellowstone National Park, Wyoming, USA
Info from Licensor: "Parking lot of Hayden Valley in Yellowstone National Park. Bison in the rut. I was outside my car watching a herd of bison in the valley. About 1/2 mile away, I saw about 20 bison running. When they got 300 yards away, I told the people next to me, 'We better get in our cars.' As soon as I shut my car door, these two bulls came out of nowhere."
