Up on Ekonk Hill the fields run out to stone walls stacked long before anyone thought about lawns, and on a clear September afternoon the view goes for miles. HAWKINS MAINTENANCE LLC. keeps the green part of that picture in order — mowing, trimming, edging around beds and walkways, and clearing the leaf drop once the maples begin to let go. Sterling ground is rocky and its yards are rarely square, so the work is as much about reading a property as running a machine. The reward shows up at dusk: even turf, a defined line where grass meets gravel, nothing left scattered. The route runs through Sterling and the neighboring Quiet Corner towns.
