15 years of nearly continuous bike commuting.

I'd tried it a few times, and enjoyed it. The Friday before Katrina hit New Orleans, though, I looked at the gas prices as I rode home and thought, "That's about to go sky high." A dozen yards up the road it hit me: "But I don't have to pay that to get to and from work." So I became a regular cycling commuter.

About the only things I pass on include snow or ice (if we're going to play bumper cars, I want 3,000 pounds on my side); heavy rain in the 30s, lightning, and illness. I can usually ride on days with thunderstorms because they're usually gone within half an hour.
