In Hubbardston the woods are always leaning back in — maple, white pine, and a tangle of brush that would take a yard back in three summers if nobody stood in its way. Central Mass Junk Solutions works the lawns strung along this town's dirt roads and old stone walls, mowing, trimming, and cutting a clean line where grass ends and forest begins. The spring cleanup pulls winter's fallen limbs and matted leaves off the turf; the fall one sends it into the cold breathing. Mulch goes down dark around the beds so the green reads greener. Out here, a mowed field standing up against deep woods looks like something somebody decided on purpose, and that is exactly what it is.
