New Boston is a town of hills and one river, and the Piscataquog decides a lot — where the roads bend, where the fog sits, how long the snow holds on a north-facing drive. Landmark Landscaping LLC works both halves of that year: plowing and clearing when the hill roads go slick, mowing, trimming, edging and landscaping when the valley greens up. Steep gravel driveways take patience in February and a careful hand in July, and neither is a shortcut job. There is something plainly good about a cleared drive at first light with the common still untouched down in the village. Then April arrives, the rake comes out, and the whole cycle starts over.
