Info from Licensor: "This video was taken out of the back of a snow coach en route to Mammoth in Yellowstone Park. Before the video was shot a couple of bison were running fast around a field and then headed off down the road. The snow coach followed. Whilst stationary, the remainder of the obstinacy suddenly appeared charging toward the coach from behind."
