I'm going to New York and I thought it would be cool if I could go all the way up the One World Trade Center by stairs. When I google it I find lots of news about stair races and stuff like that, but nothing about a single person showing up and doing it by himself.
So can I just do it, get in at the ground floor and climb the stairs all the way to the top? Or would there be any problems or bureaucracies involved? I have no idea what's it like there and it doesn't seem like something people do all the time.
