Out along the Arsenal Street corridor, where the lots are wide and the trucks are big, winter gets measured by how quickly a parking area can be made usable again. Henderson Products (USC-NY) works snow at that scale — commercial lots opened lane by lane, aprons and loading areas cleared, banks pushed back off the pavement instead of left to creep inward. A lot done right does not merely have paths cut through it; it has all of its parking back. Walkways and entries get cleared and treated so the doors function as doors. There is an order to a swept black lot under a gray Watertown sky that is hard to explain and easy to admire.
