If New York City streets could talk they probably would never shut up.  They would go on and on about tales of the people who came before us.  A new book explores the stories of many iconic New Yorkers dating back hundreds of years.  It’s calledFootprints in New York: Tracing the Lives of Four Centuries of New Yorkers.  The authors, James and Michelle Nevius, a husband and wife tour guide team, are our guests on this week's Cityscape.
