"UNDER CITY" Exploring NYC's Tunnels

My guest tonight is STEVEN DUNCAN. Mr. Duncan is an urban historian & photographer. “Undercity” is a mini documentary made by Mr. Duncan and videographer Andrew Wonder about exploring NYC subway and train tunnels and climbing bridges. Their adventures were recently featured in the New York Times and on NPR. In Steve Duncan's own words: "I try to peel back the layers of a city to see what's underneath. From the tops of bridges to the depths of sewer tunnels, these explorations of the urban environment help me puzzle together the interconnected, multi-dimensional history and complexity of the great metropolises of the world." www.undercity.org
