When a storm settles over downtown, the Tower Building goes half-erased and the Kimball Street bridge turns into two rows of lights over black water. Skyline Tree Service and Landscaping is out under that sky pushing snow, working drives, lots and the walks that lead to a door. The job is simple and unglamorous: get the pavement back, put the pile where it will not refreeze across the path, treat what the blade cannot reach. By morning the city looks like it shrugged the whole thing off, and a piece of that is one plow at a time.
