Lets be honest. Many of us city folks find little time to exercise and it shows. Just look around at the growing number of out of shape people around us, and heh, we may even be one of them. This ad by Sydney Cycleways is inspirational. The words of the guy in the ad says it all, "In a car, you just get in and get out. In a way, you are missing out on the whole journey!"
I hope you give riding to work a try!
