A group of about 50 or more tourist surrounded a bison in Yellowstone National Park, near Old Faithful. A little too close for the big bull's comfort. Some were standing as close as 5 or 10 feet away.

At some point the massive animal became a bit uncomfortable with the close proximity of the people and changed.

This video shows a 9 year old girl being rammed and tossed high into the air.

The National Park Service said in a statement that the girl was "assessed and treated by a park emergency medical providers, and later taken to and released from the Old Faithful Clinic."

The video, below, is a public service announcement that we can't seem to play enough, yet these tourist never seem to hear it.
