I've been biking a lot lately, out of necessity. Getting to school is a 5.5 mile ride, so I must average ~65 miles a week? Until Brendan pointed it out, I didn't I know that practically all of my commute is through the most expensive ZIP code in the country: 94027 (Atherton). It would be easier to tell if these driveways weren't 100 yards long with gated entrances :) Another cool part (and probably related) is crossing Sand Hill Rd, home of the venture capitalists that pump out 40% of that kind of funding in the US. I think that's the number I heard.
