Walkers Brook Drive at one in the morning during a storm is nothing but orange lights and falling white, and that is where HiCleaners is already working. Plowing, shoveling, walkway clearing and salt — driveways opened, steps taken down to bare pavement, well before the first alarm clock in the house goes off. Reading storms tend to blow in wet and heavy off the coast, so snow gets moved twice rather than once, because the second pass is what keeps it from setting up like stone. As the night runs on, the route pushes into Wakefield, Stoneham and Woburn. Waking to a clear drive you never heard being cleared is the entire idea.
