Parks workers came upon a live cannon ball, loaded in a cannon that is getti ng refurbished, CBS 2's Lou Young reported exclusively. The loaded artillery piece was one of two Revolutionary War-era cannons bein g stored at the park's Ramble shed near the 79th Street transverse. Preserva tion workers for the Central Park Conservancy called police about mid-day af ter opening up the capped cannon for cleaning. The NYPD released a picture of what its officers found: more than 800 grams of black powder still capable of firing, along with cotton wadding and a can nonball CBS 2's Young spotted being carried in a white cloth by a Conservanc y employee. For John Moore, who is working on a book called The Secrets of Central Park, this is a new one.
