“I like to look at places that people aren’t seeing,” says Ian Frazier, the author of “Great Plains” and “Travels in Siberia,” and the new “Paradise Bronx: The Life and Times of New York’s Greatest Borough.” “Not only do people not know about” the Bronx, “but what they know about it is wrong.”  The book, which was excerpted recently in The New Yorker, came out of fifteen years’ worth of long walks through the city streets, and on a hot morning recently, he invited a colleague, Zach Helfand, to join him on foot. They admired the majestic Romanesque-style stonework of the High Bridge, where Edgar Allan Poe would walk while mourning his wife, in the eighteen-forties; the impressively tangled connections of the interstate highway system that engineers once called “chicken guts”; and walked east to the Cedar Playground, which has a strong claim to being the birthplace of hip-hop.  

Note: The segment misstates the year Edgar Allan Poe moved to the Bronx. Poe moved to New York City in 1844, and to the Bronx in 1846.
