The Charles is still young where it slides through Bellingham — narrow, brown, half-hidden in the trees below the old mill village at North Bellingham. McKenzie Landscaping works the neighborhoods on either side of it, cutting and edging lawns from the first warm weeks until the leaves are down and carted off. Then the trucks change over, and winter nights become plowing, shoveling and sand on the steep or shaded drives that hold ice longest. Storms come in off the interior here, dry and fine at first, wet and heavy by morning — you plow twice or you plow badly. Doing it right means a homeowner walks out to bare pavement and thinks nothing of it.
