Along NW 16th in Oklahoma City the storefronts wear murals and the side streets behind them run to small, square, deeply loved yards. Sharp Edge Lawn Care works those blocks, and the name is a promise about the detail everybody sees first: the line where grass meets sidewalk, cut straight and cut deep. Mowing and trimming get a yard most of the way there; the edging is what makes it look finished. In a neighborhood this compact, one crisp front lawn lifts the two on either side of it. Come evening, when the patio lights go on, the whole street looks like somebody has been taking care of it — because somebody has.
