Yellowstone National Park in Wyoming has two herds of wild bison. Together they number 2,300 to 4,500 animals. It is not uncommon to see them grazing along the road. The National Park Service claims this is the largest population in the U.S. Apparently they are direct descendants from prehistoric times. The NPS warns to keep your distance. They may look tame. However, a bison can be very dangerous when provoked. So a telephoto lens through an open car window is my only way to appreciate this 1,000 to 2,000 pound animal.
