Biking
about three percent of the workforce
I've enjoyed riding the bike since I was a little thing, and I still do. Back then I mostly just tooled around the neighborhood or used my bike to get places I needed to go, and that pattern continues today. So no spandex yet, but I did splash out some cash for a fender and what I affectionately call the "dork rack" to make my mid-range mountain bike a little bit more useful. Last spring I started commuting to work by bike, which meant I got to ride a great deal more than I had been doing. The work-and-family situation now prevents me from doing as much of that, but that just means I have to ride on weekends like a normal person!
