Billions of dollars have been spent on securing the U.S.-Mexico border, and yet migrants have been able to cross into the U.S. illegally from the south. Many are brought over by human smugglers, or coyotes, who are paid thousands of dollars per migrant. About a decade ago, one coyote came up with a novel idea to use bicycles, which can evade the sophisticated ground sensors on the American side, to move people across the border. That coyote was known as ‘El Indio’, and his story is told by journalist Kimball Taylor in his new book The Coyote’s Bicycle.
