February is the tricky month out Davison Road: a day of thaw, a night of hard freeze, and by morning every drive has turned to gray glass. Brewers Outdoor Services works that stretch of winter with plow and shovel, clearing driveways and walkways down to the surface and treating what refreezes behind the storm. Snow in Genesee County arrives in every temper, from heavy wet loads pushed in off the bay to dry squalls out of the northwest, and each one wants a different pass. Getting there before the crust sets is most of the craft. The reward is a driveway you can walk down in boots without thinking about it at all.
