August on the Will County flatland can go three weeks without real rain, and the sun sits on a lawn like a hand pressing down. Carefree Lawn Sprinklers Inc. works New Lenox turf through that stretch — mowing at the height the grass can carry, trimming and edging, keeping the yard strong enough to hold its color until the weather relents. Green in the driest part of summer is not luck; it is attention paid week after week. The sky out here is enormous, and grass underneath it reads as care from the curb. When the cooler weeks arrive, those same lawns come roaring back.
