At two in the morning Queen Street is nothing but empty parking lots, falling snow and the orange sweep of a plow light. Johnstone Services L.L.C. spends those hours pushing lots clear, opening driveways, clearing walkways and laying down salt so that by opening time nobody knows how deep it got. A storm is a sequence rather than an event: first pass, second pass, pile the snow where it will not block a sightline, come back when the wind fills the entrance again. Southington wakes up, drives to work, and never sees the middle of the night. That anonymity is the whole idea.
