A good winter block in Ypsilanti is one where every drive on it is open by breakfast, because a street only works if all of it does. United Outdoor Services, LLC runs that idea straight through the season — plowing driveways and lots, clearing sidewalks, steps and entryways, and putting salt on the stretches that turn slick in the shade. Snow here can fall wet and heavy one week and dry and blowing the next, and each kind asks for a different pass. Learning that difference is what keeps a route moving instead of stalling. By the time the sun clears the rooftops, the work has already happened and the day belongs to everybody else.
