Bison petted in latest Yellowstone dangerous-behavior video

CHEYENNE, Wyo. -- A man caught on video petting a bison is the latest example of dangerous behavior by a visitor to Yellowstone National Park.

The bison dodges from the man, who was on a crowded boardwalk near a thermal area. Yellowstone officials warn the outcome could have been worse.

Park officials said Wednesday they're still investigating details of the video posted online July 8, including who the man was and where and when the incident happened.

On July 22, a bison charged and tossed a 9-year-old Florida girl several feet into the air after tourists came within 5 to 10 feet of the animal.

The girl was treated at a nearby clinic and released. Yellowstone officials said Wednesday they will not cite anybody for that incident.
