Quick tip - cat litter can help with traction when moving off if your/others car gets stuck. Either buy a cheap sack and leave in boot, or in extremis knock on doors!
Just been out. Lots of black ice on side roads; pavements pretty treacherous. Murco petrol station on ED Road are selling thermal gloves (men's & women's) for ?3.50 if anyone needs them. Just bought a pair - very toasty.
