Take a chilly pilly Willie. Using bicycles and the benefits of the exercise derived from using them is good for bicycle advocacy. Pointing out the alternative, what the sedentary American lifestyle - epitomized by the automobile - is, I think, good bicycle advocacy. You are not so obtuse, are you, that you can't see the connection between one form of transportation, the car, where they need bigger seats, and ours, the bike, where a higher level of fitness is often the result? Is pointing out the higher cancer rates of smokers good for non-smoking campaigns? And evidence that cagers are growing gigantic, thundering a$$es that can't even fit in their grotesque parody of a car as they flip us off on their way to the mall to get their smoothies.... Oh. Am I betraying an agenda of some kind here?
