Driving to work in snow or rain here is miserable. Additionally, the road salt rots out your car. Even rain slows cagers to a crawl. No way in hell I would consider taking anything but a bike to work. Dedication has nothing to do with it -- cycling is easier and far more practical. My car is for weekend fun and never sees rain or snow. So, yeah -- twenty-plus years of year round, bike commuting, because it's the easiest way. I kind of admire cagers because of the way they accept suffering.
