October is the month an edge shows. The grass slows, the maples on the side streets let go all at once, and the line between lawn and walk is either clean or it plainly is not. Perfect Edge Outdoor Services LLC spends the growing season drawing that line — mowing, trimming, edging, cleanups — and the cold months clearing what winter lays over it, plowing drives and shoveling walks with salt behind. Northville's older streets pair narrow walks with big trees, which makes each job a matter of patience more than horsepower. The route holds Northville, Plymouth and Canton.
