Fog pools in the Mine Brook hollow on spring mornings and doesn't lift until the sun clears the hill. Aquino Brothers Landscaping is usually out in it by then, opening the season — raking winter out of the turf, taking down the first tall growth, sharpening the line where grass meets driveway. Mowing carries them through a humid Somerset County summer and on into the leaf work. Then the year turns, and the same trucks come back with plows and salt to clear drives, walks and lots while the hollow is still dark. Two halves of one year, both spent on the same handful of streets.
