By the third week of September the aspen above Idaho Springs turn all at once, and the light coming down the canyon takes on a color that makes any patch of green look better than it has a right to. RIG Lawn Care and Snow Removal spends those weeks finishing the year properly — final mows, edging along drives and walls, cutting back the summer's growth, fertilizing before the ground closes, aerating, and clearing beds and leaf litter. High-country lawns get one shot at fall; whatever is left lying in October is still lying there in May. So the last cut of the season gets the same attention as the first one did. Afterward, raked to bare and put to rest, a yard at this altitude simply looks ready — which, up here, is a compliment.
