From the West Mifflin hillsides you can look down on the Monongahela and the trail that follows the old mill grade toward Homestead, and in October that whole corridor turns rust and gold. Renk's Landscaping &Lawn Care, LLC keeps the lawns above that view cut and trimmed, with the borders run sharp, while the leaves come down around them. Autumn mowing is a chase — the grass slows but the falling doesn't — and a yard kept up through November wakes up better in April for it. There is real pleasure in a last pass at dusk with the valley lights coming on below.
