Normally you're not one for crazy antics, but when it comes to saving the environment, you're paring down that carbon footprint like a real pro. Get ready for winter commuting a la cycling. That snazzy road bike probably isn't the most appropriate machinery for wet, slick roads (especially when the snow starts to fall). So consider buying a junker, or better yet, a used mountain bike (check the freecycle website): that way, you'll always feel stable, and if the metal gets a bit rusted, so what?
