November empties the trails above the Whirlpool, and the rim wind takes on that iron edge that means the season has turned for good. That is when Villani' Lawn & Landscape LLC. goes to snow removal, clearing parking areas and driveways across Niagara Falls and salting the walks that glaze over the moment the sun drops behind the treeline. A squall off the lakes does not announce itself politely; it shows up at eleven at night and is still going at six. So the truck heads out and stays out, and the measure of a good night is a row of properties nobody has to think twice about. Winter is loud in this city — this work is what keeps it from getting in the way.
