In December the oaks along Forest Avenue stand bare and enormous against a sky the color of pewter, and the borough goes quiet in a way it never manages in July. That is when Down2Earth Tree Service, LLC turns to snow — plowing driveways, clearing walkways, laying salt where the ice wants to set up. Weather in this corner of Bergen County has a habit of arriving after midnight, so much of the work happens by headlight, one property to the next, ahead of the alarm clocks. There is no arguing with a driveway that was under eight inches at two in the morning and is bare blacktop by six. That is the entire point of being out in the dark.
