Some mornings the fog lifts off Sylvan Slough and sits in the yards until the sun gets high enough to burn it away. Adams Lawn Care works the hours after that, when the grass has dried enough to cut clean and the passes hold their line. The work is mowing, trimming, edging and seasonal cleanups across South Moline and the streets that slope down toward the water. There is a particular satisfaction in a lawn cut in straight rows and edged along the walk, so the border between green and concrete is a line you could have drawn with a ruler. That is the whole of the job, and it is worth doing exactly.
