Late August on the west side, light comes slant through the big maples out toward Rouge Park and every lawn still holds the heat of the day. Trim Masters Lawn Care Services spends that hour on the parts people skip — the trimmer along fence posts and porch skirt, around the mailbox, tight to the garage slab, until a whole yard reads as one continuous line. Their work is straightforward: cutting, trimming, edging and hauling off what falls, on a schedule so the grass never gets ahead of anybody. Summers here swing from a week of thunderstorms to a week of dry sky, and a lawn shows both, which is why the route keeps coming back around. Roll past at sundown and you can tell where they've been — stripes laid straight, curb line clean, not a blade left on the walk.
