Storms tend to announce themselves from the northwest, sliding down off the Blue Hills toward Stoughton with the temperature falling all the way, and that is when Ventresco & Son Landscape Management goes to work. Nights are spent on the long circuits — Route 138 through Cobb Corner, then back into the side streets where the drifts pile against garage doors and nobody can get out until someone comes. Plows push, shovels finish the corners no blade can reach, and salt goes down where the melt will otherwise glaze over by four in the morning. It is unglamorous, cold, repetitive work, and it ends with a whole neighborhood able to leave for the day as if nothing had happened. That is the point of snow removal: to make a hard night look, by breakfast, like an ordinary one.
