Forgive me for moralizing ( ) but I think bicycle commuters are more in touch with reality than those who drive (with the exception of those who simply can't bicycle feasably.)

1) When you ride a bicycle, you are a part of your natural environment, not isolated like in a car, with the added insult of morning dj's.

2) Um, isn't that enough?

3) When you ride a bicycle, you are using human power, for which the Earth's environment is well-equipped to support, unlike the cra* that comes from tailpipes.

4) When you ride a bicycle, you are subject to the humility you have as a pedestrian, unlike the power-crazed reactions of a human who is packing 100-plus horses and high anxiety. (Don't tell me I'm crazy--I know better! )

5) When you ride a bicycle, you are saving untold thousands of dollars (which you can also spend, "helping the economy." )

6) The world population can easily support billions of bicycle riders, but billions of car drivers would turn our planet brown (not to mention our lungs.)
