This article is one of the best things I have read in a long time. It should be required reading for anyone who is visiting New York. Hell, I think they oughtta swap out those lame train videos on the airplane about how to buckle your seat belt with a video of this thing acted out in every language known to man.
If you don't know how to buckle your seatbelt, don't get on a friggin' plane. If you don't know how to follow the instructions in the article don't come to friggin' New York.
That being said, we are all really nice here.
If you follow the rules.
