How many here bike commute?

[gratuitous]

3. I have for several years

I go about 12.5 miles each way, and it takes about the same amount of time as the bus (or a little less). By all means, wear a helmet and have lights front and back.

For those contemplating bicycle commuting instead of driving, the way I did it was to set a simple goal of averaging one ride a week for half a year, and increase that to two rides a week for the second half. It was easily achievable, even in rainy Oregon, and this goal means that you cut out 30% of your driving miles and gasoline. Yeah, health benefits, smaller carbon footprint, yadda yadda, but what would your budget for gas look like if it was trimmed by 30%?
