From Noanet Peak you can see Boston stacked up on the horizon, but down in Dover the roads stay narrow and the stone walls run right to the edge of the lawns. Boylan Brothers Inc plows those driveways when a storm comes through, working in the dark along Farm Street and the long gravel approaches. The green months bring mowing on a weekly turn, along with trimming, edging and the cleanups that open and close the year. Wide properties reward a straight line — a lawn cut evenly across an acre reads from a long way off. Winter or summer, the aim is a place that looks ready.
