incedently bike to work week is may 16-22.
although largely impractical, biking is really rewarding when you get across town on one. in heavy traffic it is much faster to bike. you get a workout, no pollution. i think it makes a albeit small but still significant difference. Even disregarding pollution it is lessening the US dependence on oil. lessening traffic for you driving. lessening wear and tear on roads which your taxes go to. bikes are cool.
