Maspeth at two in the morning during a storm is loading docks, truck yards and the dark bend of Newtown Creek, everything holding still until it can be opened. B & S Maintenance Corporation works those hours — plowing lots, clearing dock aprons and fire lanes, shoveling entryways, salting the spots where meltwater always runs back. Industrial Queens does not get to wait for daylight; a lot that isn't open by five is a truck that doesn't leave. Snow gets pushed to the corners where it won't foul a turning trailer, and stacked so the next storm still has room. When the first rigs roll through and nothing slides, the night signs itself off.
