The quietest hour on the north shore is the one before the traffic starts, when the light lies flat over the bluffs at Garvies Point and every lawn in Glen Cove is still holding its dew. That is the hour Pacific Lawn Sprinklers likes for lawn work — grass upright, ground cool, nothing yet moving on the streets. July on this glacial soil can turn a yard from green to straw in ten dry days, so the care here is about consistency: mowing on time, trimming clean, keeping the whole lawn even from the shaded side to the sunny one. There is a plain kind of pride in pulling away from a property that looks composed at seven in the morning. The season winds down with cleanups, and the yards go quiet under the Sound wind.
