In late May the wind pours down off the granite of Lumpy Ridge and combs the whole valley flat. Alpine Tree Service, Estes Park works the ground beneath all that stone and sky, mowing, trimming and clearing yards so they look cared for rather than merely gotten through. Mountain turf is patchy by nature; the craft is coaxing it even, cutting to a height it can actually hold, and carrying off whatever winter left behind. By evening the fresh-cut lanes run straight to the fence line and the whole yard smells green. That is the reward, and it is enough.
