Curved, quarter-circle concrete ledge down a handicap ramp that has been waxed by rollerbladers.
Bust — ♦♦♦♦♦: There are “No Skateboarding” signs posted. Security from inside may come out and tell you to leave.
Location: The Westside Highway / 12th Avenue and 38th Street, at the ferry terminal (there are no cross streets back here, so 38th Street is an estimate.) Take the A, C or E train to 34th Street–Penn Station. Skate west on 34th Street until you hit the Westside Highway. Make a right, and skate north on the parallel bike path for approximately four blocks until you hit the ferry terminal on your left side.
