Saturday morning on a residential street in Alamosa: sprinklers ticking, air still cool enough for a jacket, the sun already sharp at this altitude. Lovato Lawn & Maintenance moves through it with mowing, trimming and edging, cleanups and the steady upkeep that keeps a yard from sliding backward mid-summer. Grass in the valley grows in a tight window between the last frost and the first, so a week missed shows, and a week kept shows even more. The satisfaction is plain: even passes across the turf, the boundary between lawn and walk cut sharp, clippings gone. By noon the block smells green, which is no small thing in high desert country.
