West of Northampton the roads climb — Burts Pit, Westhampton Road, Turkey Hill — and the higher you go, the later spring shows up and the earlier the first white does. RCW Landscape Construction takes those hill lots both ways. In the green months: mowing, trimming, edging and clearing work on ground that never quite lies flat. In the cold: driveways and lots plowed out, walks shoveled, sand and salt on the steep pitches where a car will otherwise slide back down. A hill drive opened before the school bus comes through is a small thing that makes an entire morning possible.
