-20C (-4F) in southern Germany in Feb 1983.
Followed the snowplough into the depot near the Munich "ringroad" as had no choice. (3' of snow except where they had ploughed)
They gave me tea in their nice heated office while the icicles between my nose and top lip melted. (yeah, painful!)
No pics as even if I'd had a camera my fingers would not have been able to operate the buttons, despite the heated gloves, trousers, jacket & socks.
45 mins later followed another snowplough into Munich but after dropping the bike 3 times I walked the last 2 miles to where I was going.
In Munich it warmed up to a balmy -13C (+9F) but that just made the snow more slippery.
I ended up stuck in Munchen for a week. Was fun!
