Bust — ♦♦♦♦♦: People have been known to get lucky, but “lucky” means over five minutes for this spot. There are cameras everywhere, and you’ll typically get one or two tries. Police are sometimes stationed inside and may give you a summons for skating here.
Location: 27th Street and First Avenue in Gramercy / Kips Bay. Take the 4, 5 or 6 to 23rd Street, skate east on 23rd until you reach First Avenue. Make a left and skate north on First Avenue for four blocks.
