The U.S. Mexico border is one of the most fortified borders in the world between two allies. Over two billion dollars a year are spent on securing the American southern border. But all it took to beat the border was the bicycle. Journalist Kimball Taylor saw the piles of thousands of abandoned bikes used by undocumented immigrants and solved the mystery of where the bikes were coming from and who was behind this amazing enterprise. His book is “The Coyote’s Bicycle: The Untold Story of Seven Thousand Bicycles and the Rise of a Borderland Empire.”
