Late October in Marietta, and the water oaks around Glover Park let go all at once. The Square fills with leaves; so do the yards off Church Street and Cherokee, ankle-deep by Friday. Total Lawn Inc. works that stretch the way it works every other one — mowing while the grass is still growing, then clearing, blowing the beds and walkways down, hauling the piles off before the rain mats them into the turf. Come the last cut of the year, the borders stay honest and the corners stay sharp. There's a plain satisfaction in a Marietta yard at dusk with nothing left on it but light.
