The hill at Fort Griswold catches weather early; you can watch a January squall cross the harbor and know Groton has about twenty minutes. McClure Construction handles the snow end of things — plowing driveways and lots, clearing walks, shoveling out the steps, and spreading salt where ice sets up on a north-facing slope. Storms off the water come thick and wet and never wait for daylight, so neither does the truck. The measure of a night's work is simple: asphalt showing end to end, no ridge left at the mailbox, a car that backs out without a second thought. Mornings after a storm ought to be uneventful, and that takes doing.
