Getting a little greener every day

On the heels of my last column about bystanders and activists, I got a tip from a reader about keeping your tires full. Turns out--and this may be old news to many of you--driving around on underinflated tires uses excess gas. So save yourself a few bucks (it cost me $56 to fill my tank yesterday) and top off your tires monthly. In the process, you can pat yourself on the back for making things a little bit greener.

*Note from Look for the recommended tire pressure on a sticker on the doorjamb of the driver-side door. Buy a tire-pressure gauge and check your tires monthly, adding air as necessary.
