tall buildings to jump off of in NYC

[BurningShipFractal]

Hello all, I am planning on ending my life very soon and i live around the new york city area. Does anyone know of some buildings tall enough to kill me if i jumped off of them, most importantly i am looking for a building with an open roof with minimal guardrails and not many people occupying the roof at any given time. I would also like to easily access said roof without much trouble. I dont care about building height as long as it can kill a 5'3 120 pound human easily, i do not care if i die in front of a lot of people.
