D'oh! You're right, 101 is a highway. I was thinking of 85 when I wrote it, but it's a local freeway, so it's not down south. The freeways aren't just the interstates, though; the Bay Area has 17, 82, 85, 87, 280, 580, 680, 880... and probably some others I'm forgetting. I think the only interstate in the area is I-80.
