Staying a safe distance from wildlife is no joke - they will charge you, as noted by REBOOT.
Last weekend in Yellowstone National Park, wildlife guide Jody Tibbitts caught a video of an elk that got fed up with a woman who got just a little too close.
According to Tibbitts, they pulled up to view an elk on the side of the road near West Thumb and saw a woman walking very close to the elk.
You can hear Tibbitts in the video warning her to back away, but before you know it, the elk charges the woman, and she stumbles backward and falls.
Fortunately, the woman doesn't appear hurt.
Tibbits then calls out to tell the woman that he was about to remind her that park regulations require visitors to stay at least 25 yards away from wild animals.
She replies, "It won't happen again!"
Tibbits said, "I bet it won't!"
