Three in the morning on the Mound Road corridor, and the lots sit empty the way they only do for a couple of hours a night — which is exactly the window that matters. BOTTOM LINE SNOW REMOVAL plows, stacks and salts inside it, so first shift finds open lanes and painted lines instead of ruts. Warren storms arrive two ways: the fast clipper that dusts everything and moves on, and the wet, heavy bands that ride in on an east wind and simply keep coming. Either way the job is the same — push it back, keep the piles off the drive aisles, keep the entries and walks treated. Watching the sky go grey over a lot that is already open beats any amount of coffee.
