As some of the bison appear to be charging straight for the family's rental car, a man can be heard pleading, "Don't, don't, don't, don't, don't, don't, don't."

"Oh, look at the big one in front of us," a woman in the car exclaims just before the bison slams into the vehicle.

"Oh man, there goes some money," someone in the vehicle remarks, noting the family had not taken out insurance on the rental.

Yellowstone has the largest bison population on public land, according to the park's website. The animals are allowed to mostly roam freely, and behave like their wild ancestors by clustering during breeding season to compete for mates.
