Oswego sits where a river finishes its long walk north and hands itself over to Lake Ontario, and the yards along that route take their cues from the water. Swifty Tree Service, Landscape, Sealcoat keeps those yards in order — mowing, trimming and edging through the green months, then clearing driveways and walks once the lake starts sending its winter back over the city. There is real satisfaction in a lawn cut in clean parallel lines while the wind off the harbor pushes the grass the other way. There is more of it in a driveway opened before the first commuter crosses the Bridge Street span, black pavement standing out against white banks. Whatever the sky is doing over the west pier, the job stays the same: leave the ground looking cared for.
