Windbreaks stand along the section lines out here, pine and spruce set in ruler-straight rows to take the edge off the valley wind. Pure Grove MI LLC keeps the ground beneath and around them in order — mowing, edging, trimming and the cleanups that come with spring and fall in Tittabawassee Township. Grass under a grove is its own puzzle, thin where the shade is deep, thick where the light breaks through, and mowing it well takes a lighter hand. The reward is a lawn that reads as one piece instead of a patchwork. Around Freeland and out toward Midland, the route runs the same way.
