Sunday morning in Dorr, six below zero, and a lot has to be open before the first car turns in. Heyboer Landscape Maintenance takes on the snow removal that makes that possible — plowing, clearing walks and doorways, and laying salt down where boots are going to land. Winter in this township gets measured in early alarms and headlights thrown across unbroken white. The truck comes through, the blade drops, and by the time the day actually starts the pavement is showing again. Quiet work, mostly finished before anyone is awake to watch it happen, here and in the towns nearby.
