Well,Will Fly, I grew up in Sussex (Midhurst) and back then (1950s) snow was a regular winter feature,often with quite heavy falls.But nothing ever came to a halt,as I recall---What vehicles there were clanked around happily on snow-chains,buses ran,albeit slowly,and no steam-train (Midhurst had a station in those days) was ever inconvenienced to the degree that our modern trains are.We walked long distances to school,in Easebourne,as did the teachers,and a cosy "glow" was enjoyed by all !! I suppose,because we EXPECTED snow,we were better placed to deal with it,although I disagree with the specious argument put forward by some of my detractors,about it not being worth London having any snow defences ----shall we disband the armed forces then ??? After all,we haven't been attacked since the 1940s !!
