Down in the creek bottoms near Chemung, cold December fog settles into the low ground overnight and freezes onto the fence wire in white fur. Mornings like that, the world is silent and slick and the plow lights are the only thing moving on the township road. Rivers Hedge Co. runs those hours, opening driveways and pushing back to the pavement edge so the mailbox and the culvert both stay reachable. Snow gets stacked where it will not slide back or block the sightline at the road, because a plow job that hides oncoming traffic is not finished work. When the fog burns off around nine, the drive is already black and clear and the day can start.
