A business stays closed until its lot is open. That is the arithmetic behind a night of plowing in Dixon — pushing the parking area clear, stacking snow where it will not swallow the good spaces, then shoveling entries and salting the walk to the door before the first car turns in. Storms cross open farmland here with nothing to slow them, and drifting can undo an hour's work along an exposed edge, so the route gets checked a second time. Bare pavement by opening hour is the entire goal. Dixon, Amboy, Franklin Grove, Ashton and Rochelle.
