Nick Hornby interviews David Simon, of The Wire fame:

There are two ways of traveling. One is with a tour guide, who takes you to the crap everyone sees. You take a snapshot and move on, experiencing nothing beyond a crude visual and the retention of a few facts. The other way to travel requires more time—hence the need for this kind of viewing to be a long-form series or miniseries, in this bad metaphor—but if you stay in one place, say, if you put up your bag and go down to the local pub or shebeen and you play the fool a bit and make some friends and open yourself up to a new place and new time and new people, soon you have a sense of another world entirely. We’re after this: Making television into that kind of travel, intellectually.
