Late afternoon in Concord, the gold dome catches the sun over Main Street and the light goes warm on every lawn in the neighborhoods behind it. Lawn Jobs LLC spends those hours mowing, trimming and edging, keeping mulch fresh in the beds and hedges cut to a shape that holds. Spring cleanup rakes out what the plows and the cold left behind; fall cleanup and leaf removal keep the maples from smothering the grass. The pleasure of the job is a plain one — a yard that was shaggy at noon and squared away by supper. A capital city is still a city of front lawns, and they are worth the time.
