Head over to http://www.youcanbikethere.com/user/register to register as a participant in this year's Bike to Work Day. Registration lets the Metropolitan Transportation Commission know just how popular cycling is in San Mateo and Santa Clara Counties. Oh yeah, you can win some prizes, too!

Bikes, bags, and hydration packs will be prizes available to those who take the Bike to Work Day pledge. Let the Bay Area know that Silicon Valley and the Peninsula take their cycling seriously!
