"...the growing scarcity of motor fuel imposes an obligation on those who don't need it not to use it lightly, regardless of their ability to pay for it. To our way of thinking, this includes most households in places designed before and without cars: places like Portland. We want our farmers to have motor fuel, and industry, and freight, and mass transit. But for mere personal or family transport in town, for those of you not yet incapacitated by decades of forfeiture: reclaim the legs and lungs of your ancestors for your one and only life ON YOUR BIKE!"
