It has to be said, although this winter has been pants for snow at low elevations, the air frosts this season seem to me to have been exceptional. I work in a job that means I'm up at 4am and defrosting the car has become a chore! Started early as well, from late October/early November which for sea level in Port Seton on the East Coast is unexpected. 6 degrees here just now so the first time this week I won't have to defrost the car!
