North of Syracuse the land goes flat and open, and that is exactly where the lake-effect bands off Ontario like to unload. AAA Quick Plows & Lawns Inc works those Clay mornings — headlights swinging into a driveway at four, blade down, a clean lane opened before the coffee upstairs has finished brewing. Come May the same trucks trade steel for mower decks, and the sandy, level ground that holds snow so well grows a lawn wanting a cut every five days. Snow plowing, driveway and walkway clearing, mowing and trimming: two halves of one continuous year. The pride is in the finish — a lot squared off, a lawn striped even, nothing left half-done.
