East of Milton village the fields open up and the whole Green Mountain wall stands along the horizon, Mansfield the last thing to lose the light. Summer evenings out there run long, and a lawn cut late in the day keeps its stripes until dark. Barden Outdoor Services mows, trims and edges through the growing season, then clears the yard down in autumn when the maples let go all at once. Something settles at the last pass of the mower, when the ragged part is gone and the shape of a property comes back to it. That is the whole of the job across Milton and the towns beside it, week after week.
