Before first light reaches the brick mills of the Salisbury Plain valley, the truck is already idling at the end of a Brockton driveway — blade down, headlights making a clean gray channel through the snow, the walk to the front door opened before anyone inside has found their coffee. ND Cleaning & Tree Service Inc. keeps the yards of this old shoe city through the long green stretch of summer too, mowing and landscaping streets of triple-deckers where every lawn runs right up to the sidewalk and shows exactly how it was cut. There is a plain, physical satisfaction in the result: grass laid even to the curb, an edge drawn straight along the front walk, a dooryard that reads as tended from halfway down the block. Their hands go indoors as well, into interior remodeling and carpentry, but it's the outside work the neighborhood sees first — the drive cleared before dawn, the yard holding its season, one Brockton address after another.
