Elk make these weird whistling noises to communicate with each other and they serenaded our campsites at night.

American bison (often incorrectly called buffalo) are native to North America, but only survive today in a few places. They are protected in Yellowstone Nmational Park and roam freely aroud meadows and over roads.

Park literature warns repeatedly that although bison may look fuzzy and calm, they can sprint faster than a human and gore you with theit sharp horns. In spite of this, we were repeatedly saddened to see people in the park treating the bison disrespectfully, bumping them with their cars and throwing rocks at them.
