August in Northfield Township is heat sitting on hayfields, gravel dust hanging over the back roads, and grass that puts on an inch every time it rains. Rob's Mowing and Landscaping keeps up with it — weekly mowing, string trimming around posts and fences, edging along walks, hauling clippings and brush away. Out where the subdivisions thin into farmland, a lawn kept sharp is a small argument with the wildness at the property line, and it is a good argument to win. The trimmer work around a mailbox post is where you can tell who was paying attention. Northfield Township and the roads out toward Whitmore Lake and Hamburg make up the territory.
