Sumner sits up in the hardwood hills where the West Branch of the Nezinscot works its way south, and every October the whole town turns the color of a struck match. Mitchell Tree Service LLC keeps the lawns in that country — mowing, trimming, edging, and the spring and fall cleanups a hillside property in Oxford County genuinely needs. The ground rolls here, and a lawn cut well on a slope will always look better than a flat one, the light running down it in long bands. West Sumner and East Sumner are small enough places that a tidy dooryard gets remarked on at the store. Doing that kind of work carefully is the good part of the job.
