Fog sits on the Quaboag River most mornings in Warren, and it burns off just about the time the mowers start. Bruni Landscaping works those river-bottom lawns and the ones up the slope behind them, cutting on a schedule the grass can hold and trimming close where the machine cannot reach. The line along a walk or a driveway is where the care shows, so it gets its own attention every visit. By late day the valley light goes long and low across a yard that has been put right, and that is the whole point of the trip. Lawn care for Warren and the towns nearby.
