There is one April morning in Brighton when the grass finally means it, and the first cut of the year is a genuine pleasure. Pinnacle Landscaping starts there and keeps going — mowing on schedule, trimming what the deck misses, hauling off a winter's worth of dead stems and blown-in debris. Between that morning and the last cut in October a lawn is either kept or lost, and keeping it is mostly a matter of showing up. Late in the day the light goes long and low across the plains, and a fresh-mown yard looks like a made bed. That is the picture worth working toward.
