"The Hour of the Wolf" is the hour between night and dawn. It is the hour when most people die. It is the hour when the sleepless are haunted by their deepest fear, when ghosts and demons are most powerful."
... It is also the hour when the flipping snow ploughs have a gathering underneath the bedroom window in order to take away the snow pushed aside the streets during the day.
Please let us know who has designed the piiping device activated by reversing - can it not be turned off during the hour of the wolf?
