Update – May 2013:
The building installed a bench made out of small metal bars on the run-up to the manual pad. You can still hypothetically skate it, but not really.
Spot: Low recycled plastic ledges, a four stair with a low kinked rail, and some weird tanning benches that an art student could probably figure out a way to skate. Crowded during weekdays with office workers, crowded during warm nights with homeless people.
Bust — ♦♦♦♦♦: There are “No Skateboarding” signs posted. Security will inevitably come out and tell you to leave, which is odd because there’ll be someone nodding off drugs three feet away while they do so.
Location: 34th Street, in between 8th and 7th Avenues (closer to 8th, across from Penn Station.) Take the A, C or E train to 34th Street–Penn Station, and skate a quarter of a block east on 34th Street.
