Author Hector Tobar on what it means to be Latino

What does it mean to be Latino? Author Hector Tobar took a 9,000-mile road trip across the country last winter exploring exactly that. In an essay for Harper’s and a forthcoming book, “A Migrant’s Light,” he captures the history and experience of Latinos everywhere from Los Angeles to Texas, Florida and New York. He talks to Jeffrey Brown about what he saw and how he thinks about his own identity.
