A Bergen County storm tends to announce itself around midnight, and by two the driveways sloping down off the high ground toward the center of Midland Park are already filling in. Northeast Power Dry works those hours — plowing, clearing walkways and steps, stacking snow where it will not block a sightline, then salting the glaze that forms when the next day melts and refreezes. The whole job is measured in one moment: a car backing out at 6:40 in the morning without a second of hesitation. Return passes through a long storm keep it that way instead of letting the drive bury over behind you. Winter here is sudden and short-tempered, and the only answer to it is being out in it early.
