By July the old silver maples along Warren's boulevards throw enough shade that the grass beneath them grows in soft and uneven, and the heat sits on the pavement well past supper. Marshall Landscape Inc takes the evening hours for what they are — the best light of the day for mowing, trimming and edging, when the air finally loosens and the mower's line shows sharp against the walk. Spring and fall cleanups bookend the summer, hauling off whatever the winter and the maples leave behind. A cut lawn in that late gold light is an ordinary thing to be proud of, and they are. Warren has thousands of them, and every one belongs to somebody.
