when i first read this thread, i thought that it was more for the smaller "kid brother or sister" cities. you know, the way many ny'ers see the country as a lot of small towns and backyards between here and chicago. that's not meant as an insult though. it's just the perspective.
besides the obvious things june mentioned, really there's too many things in nyc to say that a particular set of things define it.
The way that you wander is the way that you choose. The day that you tarry is the day that you lose.
Sunshine or thunder, a man will always wonder where the fair wind blows.
