Late afternoon in Berthoud lays long shadows across the front lawns, and that is the hour when edging shows — a clean seam between grass and concrete, dark and definite. Many's Landscaping chases that line all summer with mowing, trimming, edging and seasonal cleanups, then chases a different one all winter, the sharp cut of a plow blade along a driveway's edge. Both are about giving a place a boundary it can be proud of. Walks get shoveled down to the concrete and salted where the shade lingers past noon. The tools change; the standard does not.
