Behind West Springfield the land climbs into the Bear Hole woods, and squalls that hang up on those hills can keep dropping snow on Elm Street long after the radar has gone clear. Green Valley Landscaping runs through it: driveways plowed, walkways shoveled, salt and sand where shade keeps a patch of ice alive all week. When the ground lets go in April the blades come off and the mowers go on — weekly cutting, trimming, mulch, and the clearing rounds at each end of the growing year. Both jobs come down to the same discipline: arrive early, and leave the place usable. West Springfield and the towns next to it.
