North Attleborough keeps two calendars, and BCM Landscaping Inc. works them both. In June the grass off the Ten Mile River comes in thick and fast, and the payoff is a cut lawn with a crisp edge along the walk, the beds trimmed, the clippings blown off the drive. In January the same streets run under headlights, plow down, sand where the slope by the garage wants to glaze, so a household steps out to pavement instead of a wall of white. The old jewelry-shop blocks downtown and the wooded rises above Falls Pond shape the work — narrow dooryards, stone walls to mow around, long grades that hold ice after the sun has forgotten them. Mowing, trimming, seasonal cleanups, plowing and salting: one town, tended in whatever weather it hands over.
