It's not too late! If you are on the West Coast you can still ride your bike today on Strava's sponsored Global Bike to Work Day, but if you miss it; you still have 3 weeks this month to give it a try! Don't let those naysayers and negative nancies deter you. If they give you any trouble send them my way for a nice knuckle sandwich of reality!
Enjoy the wind in your face while your fellow clown car compadres are smothered in highway smog!
