Do you have more impact as a bike commuter or by taking a job that promotes biking and walking but will require driving? I suspect (and hope) that the answer is the second option, because I accepted a job that will put me in exactly that position. I am terrified excited about this opportunity, but the driving to work every day is a hard pill to swallow. Time to explore carpool and ride-share options . . . .
