They called themselves The Chasers. Twelve young men, eleven Mexican-American, one Jewish. Tucson High School, Class of 1959. "More club than gang," they were inseparable -- also cool, smart, and slightly dangerous. At a high school reunion 50 years later, the remaining Chasers spoke about what their adult lives owed to that youthful solidarity. And one of them, Renato Rosaldo, has created a poetic collage of those conversations, a new book titled The Chasers.
