1981/82 was something to witness, that was cold, my sister had a burst tap, and when my Dad and i went over there to pick one or two things up for her, the carpet crunched under our feet, as the ice in the carpet had frozen solid. Alsp had 6 foot drifts, 18" of level snowfall, minimum temp that year was over in Shropshire - Shawbury i think, it touched -26C.
