New Yorkers really DO live on a mental and cultural as well as a physical island. My mother, who grew up in Queens, pretty much viewed the entire US (and perhaps the world) as being divided into two regions--New York City, and everywhere else.
I don't do nightclubs like most people my age do, I don't see the trill in paying $50+ to get into a club with music so loud it gives you a headache and drinks that are almost $20 each, compared to females that get free cover and free drinks, its BS.
I never "got" the night club/disco/video bar/etc "scene", even when I was the right age for it. I don't understand why the music has to be so loud. But then i also don't enjoy dancing, so that might have something to do with it.
As to drinks, Vegas is the quintessential place for free drinks. Paying for them isn't stupid, but paying the hyper-inflated prices I gather night clubs charge, strikes me as moronic.
