Friday is Casual Commute Day -- the third annual initiative sponsored by Capital Area Transportation Authority that encourages residents to reduce their carbon footprint, according to the Lansing State Journal.

It's not just about riding the bus (although that works!)... car pooling, walking and biking are all options the agency wants you to consider.

If you register to participate at casualcommute.org you'll get a Biggby coupon and a chance to win prizes.
