Every season thousands of people descend on Yellowstone National Park. For most it's an experience of the lifetime, and for all the right reasons: wildlife sightings, scenery, camping with family. You get the picture.
But some folks leave Yellowstone with the sort of memories they'd probably like to forget and, perhaps, a scar or two.
"Some of the greatest visitor challenges we face are people approaching wildlife too closely," park spokesman Al Nash said. "They try to get too close to everything."
Because bison and elk are the park's most common animals, they account for the majority of human-wildlife encounters, Nash said. Some folks seem to believe bison, elk and even bears and wolves are tame, Nash said.
They're not, suffice it to say.
So if you see a bison, elk, bear or any other sort of animal and want to get a little closer for a picture, just don't. You don't want to end up on this list.
