In Hazardville the Scantic River keeps moving all winter, black water under white banks through Powder Hollow, and the snow comes down over it in the small hours. That is the shift Classic Landscape Associates LLC works — plow down, lot after lot, drive after drive, while the village sleeps. Salt goes where the ice wants to form: the shaded turn, the low spot at the foot of a slope, the walk beside the door. Morning arrives and the pavement is simply there again, dark and open, as though the storm had been an idea rather than fourteen inches. Enfield never has to think about it, which is the whole point.
