I don't ride my bike to save the world. I do it because I enjoy it.
If the world is a little healthier because of me - awesome!
If I'm not making an ounce of difference because global warming is a hoax - awesome!
Shut up and ride! That's the only thing we can agree on, so go keep the peace. Ride.
Now, if you'll excuse me, I need to go idle my car for 20 minutes so that my neighbors don't think I'm a weirdo.
