Norfolk keeps its own weather. Up here past a thousand feet in the Litchfield hills, morning fog lifts off the village green late and the nights stay cool enough that grass grows slow, thick and deep green well into August. Green Top Lawn LLC works those upland yards on a simple rhythm — mow, trim, edge, clear what the maples let go — so a lawn on a sloping lot reads as tended rather than merely cut. There is a real satisfaction in the last pass of the day: the stripe laid straight along an old stone wall, the clippings blown off the walk, the light going gold over Dennis Hill. Summer is short in this town, and a lawn worth showing off is worth the trouble.
