Three in the morning on the Route 9 corridor, and the lots sit empty in a way they never are otherwise — only the pole lights, the falling snow and the sound of a blade. Mullaney Property Management works that hour so the people who fill those lots at seven never think about the snow at all. Plowing, stacking the piles where they will not eat parking spaces, taking entrances and walks down to the surface. A commercial property has to open on time, and there is no partial credit on that. Mullaney clears snow in Wappinger and the neighboring towns.
