[caption id="attachment_810" align="alignleft" width="200" caption="How often do you put your car in park?"] [/caption] Yesterday was World Car Free Day, and I hope you joined folks all over the world in leaving your car at home and put on your walking shoes, getting on your bikes or riding your local transit system. I think World Car Free Day is a great way to reflect upon the harm cars can do to our environment, the state of our public transit systems and the way our cities have developed. But as responsible citizens, we should do better that once a year. Have you contemplated leaving your car at home often? Say, once a week, or once every two weeks? Do any of you take part in a car-sharing program? Cars produce over 10,000 pounds of carbon dioxide each year (not to mention the amount of mining that goes into manufacturing cars and harmful petroleum extraction), so imagine the difference if we all dramatically changed our driving habits. Cycling and using public transit are great ways to explore a city, and think of how much less frustrated you'll be because you don't have to sit in traffic. How have your driving habits changed? I realize some of you might live in rural communities, where you have to be much more dependent on cars, but have you been able to make any changes? Don't forget to enter my giveaway and you could be one of two winners. I'll announce the winners on Friday!
