Sugden Reservoir holds the first light of a Spencer morning long after the roads have woken up. A. Arsenault & Sons works the yards on the slopes above it, laying mowing lines straight across ground that rolls the way central Massachusetts always rolls, up and then gently down again. There is real satisfaction in a clean edge along a walk, in beds mulched dark before the heat comes on, in turf fed and seeded until it closes over its own thin spots. These hills are old and patient, stitched together with stone walls, and a well-kept lawn belongs in that company. Come evening the mower goes quiet and the grass keeps its stripes right into dusk.
