In the evening the Grand Mesa goes flat and blue above Olathe, and the light lies down long across the yards on the north side of town. That is a good hour to look at a lawn, when every ridge the mower left shows itself. Specialty Lawn Services Inc. mows, trims and tends yards through the growing season here, holding them even where the valley sun can be hard on turf by August. The work is repetitive on purpose — same lines, same week, same careful pass around the trees — because that is what makes a yard look cared for. Watching a place keep its green from May to October is its own kind of return on the effort.
