The bison has been named the national mammal of the United States. It’s fitting, since it is estimated that 30 to 60 million bison lived in North America in the 1500s before huge slaughters took place as settlers moved westward. The bison was near extinction, down to about 300 head nationally before a handful of ranchers captured orphaned calves and began raising them. Today the population has grown, with bison found in national and state parks, as well as several private herds being raised for food. I toured the Broken Wagon Bison Ranch in Hobart, Indiana, where I learned more about bison and had a chance to meet the herd up close and personal.
