I enjoy a little bit of an adrenaline rush as much as the next guy--- Hanging out with Bison might not be the best time to get that rush.   Take a look at this video as some tourists get a little too close to a Bison and get a heck of a scare. While enjoy the beautiful scenery in Yellowstone National Park I always enjoy watching the "not-so-bright" tourists.  These folks always make everyone's lives  more difficult, and sometimes more amusing!  Run Little Buddy Run!
