Four in the morning on a school day, and the sound that wakes half a street in Union is a plow blade finding pavement. Russo Outdoor Solutions LLC is out ahead of the buses — driveways opened, aprons cut back after the road crews pass, walkways shoveled and salted so nobody starts the day on ice. Storms in this valley can drop wet, heavy inches or dry squall snow, and each one wants a different pass. The work is finished before most people look out the window, which is how it should be. Residential and commercial plowing across the Town of Union and its neighbors.
