East of Littleton the land flattens out and simply keeps going, and the wind that crosses it has nothing at all to slow it down. High Plains Lawn Service takes its name from that country and its work from the yards inside it, mowing and trimming lawns that have to hold their own against dry air, big sun and a horizon where you can watch weather coming an hour ahead. Grass out here is a decision somebody made and keeps making. Cutting it even, week to week, is how that decision gets honored. On a still evening those green squares set against all that open tan country look like small deliberate kindnesses.
