On a July evening the light off Canobie Lake goes gold and low, and the streets above it hold the smell of cut grass for hours. M.B. Lawn & Plowing Service, LLC mows those yards on a steady weekly turn, trimming fence lines, edging walks, and clearing clippings so the finish reads sharp from the road. Come December the same driveways ask for a different kind of attention, and the plow goes on the front. Salem weather rarely arrives politely — freezing rain on top of six inches is an ordinary Tuesday — so drives get opened, then widened, and entries get cut down to something a person can actually walk on. Cleanups in April and again in November close both ends of the year.
