By mid-August the metro-east air goes thick and still, thunderheads building over Missouri all afternoon before they cross the river and break over Belleville. Lawns here live in the long argument between fescue and zoysia, and Oasis Lawn Care LLC mows, trims and edges straight through it, week after week, keeping a yard even when the heat says otherwise. Autumn hands over the leaves, and the leaves get gathered and hauled before they mat down over the crown of the grass. Then the cold makes everything simple again: open the driveway, clear the walk, treat the ice at the bottom of the steps. That first look out the window at a property already taken care of is a small, good feeling, and it is the point of all of it.
