By seven on a July morning the shade is still holding along the streets near Kracklauer Park, and that is the finest hour of the day to be cutting grass in Mundelein. Campos Landscaping takes it — mowers off the trailer, lines laid straight across yards that roll a little the way Lake County ground always does. Trimming around the oaks, edging the walks, clearing the cuttings off the concrete before moving on. Grass grows hard here between the kettle lakes, thick and quick after a rain, and staying ahead of it week to week is the whole discipline. The result is turf that looks unbothered — even, green, finished — which takes more doing than it lets on.
