May 12--16 is Bike to Work Week, part of the League of American Bicyclists' Bike Month. I have been peddling to work frequently since starting grad school. I have only driven on a few workdays since September. Yesterday I rode my bike to work. After work I rode an extra 72 km. For about a third of the ride, I rode with three guys from a local bike shop. Man, are they fast. I'll probably go on a ride tonight.
