New York Harbor's Dirty Little Secrets
We all know what lies beneath New York. But is there anything cool to be found underneath New York Harbor? How about a freight train, a giraffe skeleton, $26 million in silver bars, ice cream trucks, and lots and lots of dead people!
(And of course, until recently, that airplane that landed on the Hudson River.)
