A family on vacation at Yellowstone National Park was caught in the middle of a massive bison stampede that damaged their rental car.

Video shows more than a hundred of the animals, of all sizes and ages, charge vehicles that are stopped on the road.

One bison hit the Delle Chiaie family’s car, smashing the front windshield of the vehicle.

“I can’t believe we didn’t take the insurance,” said one man on the video. “The whole hood is crushed.”
