Author and New Yorker contributing writer Ian Frazier has written a new cultural and social history of the Boogie Down Bronx. Paradise Bronx: The Life and Times of New York's Greatest Borough  was written over a fifteen-year period as Frazier walked all around the borough, observing its physical landmarks, people, and unique quirks. Frazier discusses what he discovered during his walks and what sets the Bronx apart from other boroughs, and we take your calls.
