“To tell the history of the Americas is to tell the story of bovine expansion. Settlers may have made the Wild West and the frontier, but they followed in the wake of their bovine brother. No other animal has so shaped a culture. So many American icons are associated with the cow: the cowboy, the western, the rodeo, the hamburger, the steak house, the Marlboro Man, the very notion of the frontier itself. The story began more than five centuries ago.”
