First light in Twin Falls comes up flat and gold along the rim of the Snake River Canyon, and by then the mowers are already loaded. KJ Lawn Maintenance & Spraying LLC works the yards off Blue Lakes and the side streets branching from it, cutting, edging and treating turf so it holds its color through a high-desert summer. A lawn out here is something somebody decided to make happen — water carried a long way onto ground that grew sagebrush before it — and it deserves to be kept well. There is real satisfaction in a straight edge along a driveway and a mowing line that runs true to the back fence. Weed and turf spraying keeps the dandelions from taking a whole block, one address at a time.
