In Great Barrington the Housatonic slides under the Bridge Street span carrying a low green light, and the yards along it wake early. Brick Hill Lawn & Landscape LLC keeps those lawns mowed, trimmed and edged through the long Berkshire summer, then comes back in the dark half of the year with a plow blade for the same driveways. There is one kind of satisfaction in a lawn cut in clean parallel lines on a June evening, and another in a driveway opened to bare pavement while Main Street is still asleep. Spring and fall cleanups bracket it all, hauling off whatever the maples decide to let go. Whatever the sky is doing over the southern Berkshires, the aim stays simple: the yard looks cared for, and the car gets out.
