There is a smell that belongs to Thornton evenings in summer: sprinklers just shut off, wet concrete cooling, and cut grass on the air over a whole block at once. Dream Landscape Services, Inc. builds its work toward that moment — mowing, trimming and edging done so a yard is at its best when people finally come outside. Around the Cherrywood and Skylake streets the lots are generous and open to the west, which means every lawn gets full afternoon sun and needs a cut height that respects it. Cleanups keep the beds and fence lines from creeping in on the turf, season after season. When the light goes long and low, a well-kept lawn out here looks like something out of the daydream that sold the house.
