First light in San Lorenzo comes filtered through bay fog, the shoreline gulls already loud over the flats. Symons Landscaping likes to be working by then — there is a particular satisfaction in a lawn edged and blown clean before the fog burns off and the day properly begins. The trade is maintenance in the truest sense: mowing on schedule, keeping the borders honest, trimming things back before they get ideas. On gray mornings the cut grass holds its dew and the lines look almost drawn. By the time the sun finds the Village, the yards on the route are the sharpest thing on the street.
