Cedar Mountain stands over Newington like a low dark wall, and weather crossing the valley shows itself there first. Earth Works Developement LLC watches those skies for a living — clearing driveways and lots with the plow, opening walks and entryways by hand, then treating what remains with salt and sand. Valley storms often start as rain and turn, which is the worst kind: an inch of slush that sets like concrete by four in the morning. Timing the first pass right is the difference between a clean surface and a week of frozen ruts. Newington wakes up, and the pavement is simply there.
