"Bison are the largest land mammal in North America. They are the national mammal of USA. At one time, there were 30-90 million Bison roaming most of America. They lived from Alaska to Mexico, and from the east coast to the west. Native Americans and bison have had a close relationship for thousands of years. I appreciate the massive bodies of these great animals and how they create a landscape by simply being." - Susan Easton Burns
