QUIZ: What's the ultimate mileage machine?

The Bicycle, of course! It gives you unlimited mileage using zero gas and zero oil. It's quiet, relatively fast, absolutely clean, and good for your health. Got one lying around? When was the last time you rode it instead of driving somewhere? Now's your big chance. Dust off that bike. Pump up the tires... Cool! You've got your own free, non-polluting transportation.

(Have fun, and don't forget to wear a helmet.)
