From the north shore of Sloan's Lake the mountains stack up west of the city, and in May they are still white above the greening yards below. Roman Lawn Care Service works those west Denver blocks straight through the growing season, mowing, edging, trimming and running the cleanups at either end of the year. Grass comes on fast here once the nights stay above freezing, and then it wants cutting on a schedule that has no interest in anyone's weekend. There is genuine pleasure in the first mow of the year: the lines appear, the edge gets drawn, and a yard that looked tired all winter sits up straight. Nothing complicated about it. Just done.
