Before the streetlights give up on a winter morning, the Hackensack bends past New Milford under a skin of ice, and the truck is already out along River Road. Armbruster Landscaping works the borough's short blocks and deep driveways, plowing down to the pavement and salting the walk so the first person out the door has nothing to think about. Come April the same routes turn green and the mower goes back on — weekly cuts, a clean line along every curb and apron, clippings carried off. There is real satisfaction in a lawn that holds its edge all summer on a street where the maples throw shade by three in the afternoon. When the leaves come down in one long week, they take those too.
