I've taken that shuttle a number times, but only when I'm not paying attention and I go through security at the wrong bay. The shuttle bus goes from gate 25 in the middle bay to gate 34 in the north bay. I think they leave every 10 minutes or so and the actually bus trip is something like 2-3 minutes.
