Created using the word "Save a planet, ride a bike" In a environmental twist on the comical saying, "save a horse, ride a cowboy", the saying "Save a Planet, Ride a Bike" was born. What a difference it would make if everyone rode their bike at least one day per year instead of driving a car. Bicycles CAN save the planet! And it says so on this shirt. Show your love and support for the planet by wearing this shirt proudly.
