This thread is already going off the rails. The answer is NYC. It has the highest population/concentration/variety of young females who will casually hook up with little-to-no investment. Get some online dating profiles going and clean up.
The city is so huge, there are so many people, and the "vibe" everything is just incredibly conducive to hooking up. Every girl that lives there is not from there, and they just live in NYC for the crazy/exciting/adventurous experience of living in the Big Apple and the "Sex and the City" mindset is in full effect.
