When I started working at the university I bought a parking pass. This was a hunting license allowing me to look for a space in a gravel lot that was a twelve minute walk from my office.
A year later, when it came time to renew the permit, I said the heck with that, and bought a bike. It turns out that for what it would cost to park a car I can buy a nice bike every few years and throw in the university-subsidized bus pass for those days when the weather or my health make a bike look two wheels too few.
Recently I calculated that I have commuted to work a whopping 30,000 miles since I switched to the bike. According to the EPA’s Household Emission Calculator that's about 408,420 pounds of CO2 I didn't produce.
Besides being good for the planet my bike commute is great for my health and easy on the wallet - it has extended the life of my car by, most likely, two years.
This is worth celebrating, and it happens that Friday, May 21, is Bike To Work And School Day. Oddly enough I will not bike to work that day. Instead I will help to staff one of the many Celebration Stations around town. If you bike or bus or walk to your job that day, drop by one of the stations for all kinds of treats - coffee, fruit, donuts, candy, and chances for prizes.
Don't worry about the calories. You can pedal them off.
