From all the cities I've been to, NYC is the best. It is so huge, it's hard to even visualise. It's my mother's hometown, and we'd often visit it as children. I never felt like anyone was mean or unfriendly there in all my visits. The whole city has this electrical buzz about it. Very energetic, and always going, going, going. You can do just about anything you want at any time of the day or night.
