I glance out my kitchen window to glimpse gas prices posted by the station on the corner so when numbers start dipping, I can monitor them for a little while before racing to a nearby gas station—one with even lower prices—to fill my tank. Sound a little obsessive? You bet. Just last week, prices jumped from $3.29 to $3.59 in hours, an increase that makes me shudder when I contemplate filling up in Chicago. My ability to keep tabs on gas price drops is going to be one terrific benefit once ice and snow arrive on the scene.
