Gilcrest lies on the flat between US 85 and the South Platte, where the ditches run full in July and the corn climbs from ankle-high to overhead in what feels like a fortnight. AAA MOWER SERVICE AND REPAIR LLC. keeps the lawns of that valley cut through a long, bright Weld County summer — mowing, string trimming, edging, seasonal cleanups — and keeps the machines that do it running, with blades sharpened and mowers serviced and repaired. Out here a yard is a green square held against a great deal of dry country, and it takes both halves of the job: a steady cut and an engine that starts on the first pull. By evening the wind lies down, the grain elevator throws its long shadow up the county road, and the grass stands even from fenceline to fenceline.
