Up past Punkatasset the old cart roads run into Estabrook Woods, and in late October the light through the beeches turns the color of cider. Mr. Oliveira Landscaping LLC is finishing the year's mowing about then — edging one more time, pulling leaves off the lawns before the first heavy sky arrives. When it does, the work changes shape: plow routes, shoveled walks, salted steps, driveways cut open to the pavement while the wind is still moving snow around. January mornings out here come up blue and stinging, and a cleared drive is a genuine gift. Lawn care in the warm months, snow removal in the cold ones, across Concord and the towns near it.
