Bad things can happen if you attempt to pet a bison.
During the Sturgis Motorcycle Rally a female passenger on a motorcycle got off and approached a herd of bison that were blocking the road at Custer State Park in South Dakota and wound up being violently attacked as she got too close while taking photos. A bison charged the woman and caught her belt and jeans with its horn and tossed her around in a circle until the pants came off. Former Executive Director of the world-famous cycling event Scott Meyer, says he is amazed at how fearless people can be, and that everyone should show a healthy respect for these powerful animals.
