At Bar Mills the Saco pushes over the dam with a steady roar you can hear from the road, and in late September the valley turns every shade a maple keeps. Buxton yards run wide and open, sloping toward that water, and they take a full mowing season: weekly cuts, close trimming, edges kept clean along the drives and walks. Autumn cleanup here is a large job and a satisfying one — leaves off the grass, beds cleared, the whole property squared away before the ground hardens. Then the plows go on, and winter becomes a matter of opening driveways, clearing walks and sanding the steep spots before daylight. Buxton and the villages along the river.
