Spring reaches Riverdale as the smell of fields thawing and the first green fuzz along the ditches of the township roads. R & F Excavation & Land Management takes care of lawns in this rural corner of Minnesota, approaching each yard with an eye shaped by excavation and land work. That background shows in the details: trimming tight along fences and outbuildings, mowing that follows every rise and dip of the lot. In a place where people watch the land closely, a well-managed lawn speaks the local language. From the first April mowing to the last pass in October, the work keeps Riverdale's yards in good order.
