I'm talking native NY'ers (folks who have been here >10 years and/or those who had their formative years here) compared to tourists and out-of-staters. Believe me, the difference is stark. You (and I, I guess, since I'm 39) are from a different generation, so I don't think you would have noticed it back in the day, because NY women weren't always like this - even I remember a time when NY women were far more approachable, open, and at least made their interest known if you took that first step (looking and/or smiling). But in the last 8-10 years? There is certainly a difference between NY women and other women. It's a cultural/generational thing. All of my friends have noted this independently at various times, so it's not just me.
Put it this way: I can almost immediately tell whether a woman is a native NY'er by the way she interacts and talks with me. I'm almost never wrong. There's a reason for that.
