As a Chicago native and a current Manhattan resident I'll have to respectively disagree. The amount of single women in Manhattan is staggering, noticeable and quite frankly of higher quality. For the record - I still love Midwest women.
As a single hetero male I have never seen a single episode of Sex and the City, but I can speak wonders on what it has done for the single man in NYC (and the world for that matter). Thank you SJP...I say the former (better).
