A clipper comes down off the plains overnight, and by four in the morning Beech Daly is a single set of tire tracks. WiltonScape answers that hour — plowing out driveways and lots, clearing walkways down to the pavement, spreading ice melt on the north-facing steps that never see sun in January. Redford's streets run flat and open, so the wind gets a long run at things and can rebuild a drift across an entrance as fast as you cut it; the answer is simply going back. By the time the school buses turn onto Inkster Road, the places on the list are open and passable. That's the whole measure of a winter night's work here — whether people can leave when they meant to.
