The Farmington Valley is broad and flat-bottomed, an old lakebed with the ridge standing up along its eastern edge, and on a July evening the light crosses it slowly. Farmington Valley Landscaping keeps lawns here — mowing, trimming, edging and seasonal cleanups, the steady weekly work that holds a yard together from the first cut of spring to the last raking of leaves. There is a plain satisfaction in a lawn finished at day's end: the mower lines running true, the edge crisp along the front walk, the clippings blown clear off the drive. Farmington and the towns nearest it are the ground they cover. Lawn care, week after week, on the schedule the grass actually keeps.
