The hour before sunrise on Mill Plain Road is the bluest part of a winter day, and the plows are already three hours into it. L&C LANDCARE LLC runs storms across Danbury's west end, opening driveways so people can get out and clearing lots so people can get in. A good route is built on order and repetition — push, stack, back-drag the apron, move on, then come back and do it all again when the snow will not stop. Front walks and steps get shoveled to solid footing. What you want at the end of a night like that is a row of black driveways with white banks beside them, and the sun just starting.
