For just one week, how many car trips can you replace with walking, bicycling, or public transit?  Almost half of all trips we take during the day are five miles or less, the perfect distant for bicycling. Many of our errands are less than two miles from home, close enough to walk.

The Car-Free Challenge runs May 10th through May 16th. Sign-up online and log your miles during the week to be eligible for great prizes.

Can you go car-free just once during the week?  How about a whole day?  Or even the whole week?
