Follow the South Branch of the Piscataquog toward the Gregg Mill covered bridge and you get the measure of New Boston: water, ledge and hayfield, arranged by somebody patient. Brotherhoude Enterprises LLC works both halves of the year out here — mowing lines laid straight across summer lawns, edges cut clean where turf meets gravel — and then plowing when the valley fills with white. Storms slide down off the hills and pile deepest in the low ground along the river, which is exactly where a driveway needs opening first. There is a plain satisfaction in a dooryard cleared before the first car of the morning, and in a lawn that looks combed rather than merely cut. Home ground, tended the way home ground deserves.
