for 20s, NYC hands down pretty much. I'm always a bit bemused when I see Richmond noted as a good place for 2Os people. Its not a town I would have moved to until my 30s. (moved here from Boston).

As for NYC I remember one girl in the west village saying "you can get anything you want... except the basic necessities of life conveniently"

love visiting, would do so once a month if life permitted, but living here is sooo much easier
