Bison rams grandfather in Yellowstone Park, knocking him metres into the air

The incident occurred on Friday evening at Bridge Bay Campground near Yellowstone Lake in the final hour before sunset. Isom-McDaniel and his grandson appear a good distance away from the animal as their walk slows to a halt and they raise their cameras to take a picture. The Bison then repeatedly flops on its side in an agitated fashion before hopping to its feet. A white truck slowly approaches the scene, but after the Bison charges the truck the driver speeds off. The animal continues forward, leaving a cloud of dirt in its trail as it barrels towards Isom-McDaniel and his grandson.The pair try to evade the Bison by running through a thicket of trees, but the animal eventually caught Isom-McDaniel."The Bison hooked him with his left horn on his hip and tossed him in the air," Mike Macleod, who recorded the incident, told the Cowboy State Daily, a local paper. "He made a perfect flip and landed on his side." Mcleod continued: "He was in a lot of pain with his leg, and otherwise he was conscious the whole time, in good spirits, joking." Summer is the busiest season in Yellowstone, according to the NPS. Nearly 60% of annual visitation occurs solely during the months of June, July and August.
