I don't know what makes a person see a three-quarter-ton bison and think taunting it is a good idea. But this guy is lucky to be unharmed.

A woman driving through Hayden Valley in Yellowstone National Park earlier this week shot video of a tourist going head-to-head with a buffalo. The guy is out of his car and can be seen shouting and waving his arms at the animal.

The bison even charges the guy, but he's able to evade it.

Yellowstone Superintendent Dan Wenk said this about the video:

"The individual's behavior in this video is reckless, dangerous, and illegal. We need people to be stewards of Yellowstone, and one way to do that is to keep your distance from wildlife. Park regulations require people to stay at least 25 yards from animals like bison and elk, and 100 yards from bears and wolves. These distances safeguard both visitors and the remarkable experience of sharing a landscape with thousands of freely-roaming animals. People who ignore these rules are risking their lives and threatening the park experience for everyone else."
