There’s a ton on campus, but you get kicked out of most it right away. The main things recognizable from videos are two round ledges running against a wall, over a brick bank. There are rails, steps, etc. all throughout campus, but lurking around will increase your chances of being booted.

Bust — ♦♦♦♦: Skateboarding is forbidden on campus property. Your chances are better during holidays or summer, but there is security on campus 24/7. They’ll escort you out to the street the second they spot you, which normally does not take very long.

Location: 116th Street and Broadway or Amsterdam. Some entrances are mellower than others (Amsterdam usually grants better luck), but you’ll get kicked out regardless.
