Cherokee sits in the old coal country of Crawford County, where flooded strip pits have turned into still lakes and ducks come winging in low on November mornings. Greenwing LLC Lawn and Tree carries a little of that wild grace in its name, and its work keeps homes in town open and orderly as the leaves come down. On the tree side that means cutting back limbs that crowd a roof or hang over the drive; on the lawn side, mowing and clearing fallen leaves before they mat the grass. Grass cared for like this catches more sun and greets spring a step ahead. Under the gray southeast Kansas sky, Greenwing leaves the ground clean and the branches shaped.
