In what might be the final Yellowstone National Park touron video of April, a visitor can be seen walking up to within just a few feet of a massive bison. As one would expect, the animal didn't appreciate it and responded accordingly.
Bison require a very wide birth and are known to charge when threatened. A video posted to YouTube recently shows just how these animals can get a bit possessive with space.
A couple was recently filmed appearing to be running from a large bison herd. What comes to question though, is why were they actually running "with" the massive animals?
