What was your coldest ride?

My coldest ride was an April trip to the UP about 20 years ago. Everything was ok on the way up, but on the way down it snowed. I traveled from Bessemer, MI to the bridge. I was so cold I could barely get off the bike. When I sat in the hot tub it was like fire as my body was sensing the extreme difference. It took me 1 hour to just get to the point where I wasn't cold, but cool. It didn't help that there was a cool mist the whole trip as well.
