A couple visiting Yellowstone National Park learned the hard way why it's a bad idea to go face-to-face with a bison. The pair encountered a large bull while hiking on the park's extensive network of boardwalks, but rather than turn and find a different route, giving it plenty of space, they decided to approach and take photos from just a few inches away. One of the pair even crouched down right in front of the animal's face to get a better shot.
As you can see in the video below, which was recorded by Instagram user yesitsjen and shared this week via account TouronsOfYellowstone, this wasn't a wise decision. After a few seconds, the animal became frustrated and easily jumped onto the boardwalk, tail raised in an aggressive posture, sending the pair running.
