There never seems to be a short supply of these stories.
This video comes from Yellowstone National Park in Wyoming where yesterday several tourists were charged by a large bison.
It seems that the tourists were not giving the provoked bison enough space and, rather than leaving it alone and heading to safety, they stayed to watch what was going to happen next.
Then it charged them.
The video shows what appeared to be a small child nearly getting trampled by the large beast.
Luckily, the tourists managed to escape at the last moment, which is lucky, given how big and upset that bison looked.
It should always be front of mind when visiting areas with bison that these thousand-pound beasts could kill you in a heartbeat.
