North of Saint Johns the Blue Hills roll away in bands of gray and pale blue, badland clay that turns violet whenever a storm shadow crosses it. Blue Hills Environmental Association keeps town lawns and yards in order against that backdrop — mowing to one height, a crisp line at the sidewalk, string trimming close around posts, meters and tree rings. Spring cleanups pull out the tumbleweed and windblown litter that stack against fences all winter. Through summer the visits stay regular so the grass never gets away, and nothing sits in a pile by the fence afterward. Simple, steady care, in a place where the horizon does all the drama.
