Along the 16th Street corridor the docks are open before sunrise, and a lot full of unbroken snow at four in the morning is a business that cannot open. Jacob's Commercial Snow cleaning keeps that hour — plowing lots and drive aisles, clearing entrances, walkways and dock aprons by hand, salting the places where meltwater will freeze back into a hazard. Cicero storms rarely announce themselves politely; wind refills what was just cleared and the temperature swings all day, so the route runs again and again until the pavement is truly black. There is a specific satisfaction in a lot finished before the first car turns in, with the driver never once thinking about it. That is the entire job: nobody slips, nobody waits, everybody gets to work.
