Reader Bob Fritz has stepped up and sent some great photos of bison from out West. His notes are indented:
Anyone who has been to Yellowstone is likely to have encountered the American Bison (Bison bison). They freely roam throughout the park, and frequently block traffic on the roads. People are warned to keep their distance, but often get too close and bison attacks do happen.
Here are some photos taken over various trips to Yellowstone National Park.
