My house on Stevenson Road faces Spencer Place. A plow came down Stevenson heading east and took a left turn onto Spencer. Another plow appears to have come down Stevenson heading west and took a right onto Spencer. As a result I have some 40 of deep snow blocking my driveway. I don't understand why the plow didn't just go up Stevenson past my house and come down the other side after turning around at the end of Stevenson.
