Snow takes the sound out of Aurora; at four in the morning near McCullough Park you can hear a blade working two streets over and nothing else at all. Green Arias Landscaping and Snow Removal moves through that stillness, clearing driveways and walkways, opening lots, laying salt where boots and tires will need it. There is a music to the night route, the engine's long note, the scrape, the pause at the end of a drive. This corner of the Fox Valley can hand you four inches of dry clipper snow or a wet six that sits like poured cement, and each one asks for a different pass. Either way, dawn should find pavement showing.
