Hikers' Close Encounter With A Bison In Yellowstone National Park

While visiting Yellowstone National Park two hikers were mere feet away from a very large but care-free bison.  Although bison are one of the largest and wildest animals in America, they are relatively calm as long as you don't move a muscle, like what these hikers did.  Judging by their facial expressions, they had mixed feelings of excitement, humor, and sheer terror.
