IT'S NOT A DISNEY BISON

   A large bison meandering around a grassy hillside nearby had abruptly changed course. It was now thundering toward the group of people, headed straight for a girl. Onlookers gasped. Wordless shrieks mixed with shouts of “Oh, my God!”
   In seconds, the powerful animal had reached the child, who was trying in vain to outrun it. With a swift toss of its head, the charging bison catapulted her high into the sky like a rag doll, flipping her head over heels before gravity sent her tumbling to the ground.
   Of all the wildlife that roams Yellowstone, bison are responsible for injuring more visitors than any other animal, officials said. The largest land-dwelling mammals in North America “can be aggressive, are agile, and can run up to 30 miles per hour,” which is three times as fast as humans, according to the Park Service. Males, or bulls, can weigh up to 2,000 pounds and stand six feet tall.
