IDEAS: Do you miss Boston?
WALLACE: I miss parts of Brighton and Allston and the Back Bay very much.  But I lived there for only three years and I moved away only a decade ago. I’ll go back at some point. Sure. Ride the B Line.

IDEAS: A friend of mine thinks that Infinite Jest should be understood as a Boston novel.
WALLACE: I think a lot of the dialect in there probably doesn’t make much sense if you don’t know Boston. Boston made a big impression on me, because linguistically it’s very different than where I’m from.
