By mid-October the hardwoods on Kennesaw Mountain turn nearly all at once, and the ridge stands over Cobb County in rust and gold. Autumn Landscape Company works the yards below it, mowing through the last warm weeks and clearing the leaves that come down after. The mower keeps a lawn honest; the cleanup keeps it visible, turf coming back out from under the drift. Trimming and edging finish the shape — the walk restored to its true width, the beds given a clean border. There is a particular satisfaction in handing back a Kennesaw yard in fall, tidy under a sky gone suddenly blue.
