i think the "boston closes so early" thing is way overplayed. i'm often in SF, frankfurt, LA, NYC, nashville, and shanghai -- it's a challenge even in nyc and nashville to get anything beyond a slice of pizza or a hot dog (or equivalent) past midnight, public transportation anywhere other than NYC shuts down earlier than the MBTA, and it's a total myth that every big city other than boston is some 24-hour dance party: clubs and bars close around the same time (other than NYC and even there, the "scene" past 2am is exactly what you'd expect -- mostly non existent).
