So here is my worst winter experience.
I lived in Minnesota for several years and those 5 month winters did me in. The 2-3 feet of snow on the ground was nothing compared to the nasty cold. One year I went back to visit my sister over the Holidays. When I left there it took them 4 hours to de ice the plane. The outside temperature was 29 degrees below zero. The windchill was 87 degrees below zero. When I got back home to the airport here, I found out that the cold had frozen and destroyed all my luggage. My samsonite luggage (hard case) froze and had cracked from top to bottom. My vinyl carrying bag was shredded from the cold. My shoes, which were in that bag, came out of the luggage conveyer by themselves following my shredded bag.
