On an August Friday the Rio Grande Trail is busy with bicycles, the hay in the Marolt Open Space has been cut and lies pale in the sun, and out toward the Maroon Creek bridge the aspens are still holding their full summer green. Noble Landscapes works through that stretch of the calendar the way anyone here does — fast, because the window is narrow. Mowing keeps its weekly beat, the edger goes down every hard surface, the trimmer takes the corners a mower cannot, and the property is cleared out thoroughly at each end of the season. High country grass rewards a firm schedule and forgives very little neglect. The payoff is a lawn that stands up straight and even in that flat afternoon mountain light, with clean lines around every bed and post.
