Watch a Bison Attack Snowmobiles and a Snow Coach at Yellowstone
This just in. Bison are not fond of snowmobiles or snow coaches. I can prove that with a new video that has just surfaced where a bison went after several guys on snowmobiles and a snow coach.
WARNING: even though no snowmobiles or people were harmed in the making of this video, there is some NSFW language. The guy did spot a massive bison in his path, so that's understandable.
The encounter was captured from several angles.
This is what it looked like from inside the snow coach. Not to self: when a bison jumps up and down in front of me, he's not trying to make me laugh.
