I just pledged to use an 'alternate clean commute option' once every week in March over at the radio station KBCO! I've been wanting to ride my bicycle more and this will give me a little push. Last weekend I rode my bike to work and it felt so good. I easily forget the benefits of riding my bike- free exercise, less traffic (going to work I travel almost entirely on a bike path. I cross two roads!), saving gas and emissions.... Just to name a few. Plus, I just enjoy it! An extra perk is that by signing up I'm entered to win a schnazzy scooter.
If you live in the Boulder area and would like to pledge also, here is the link.
