I'm sorry...how cold did you say it was!?

We just got back from Tignes (yes, we were there again). I have never experienced such cold...even my eyeballs would freeze when I went outside. Yet, I just chalked it up to me being a big baby who was raised in AZ. But no, it was genuinely cold enough to freeze your winnebago!! It was -20C (-4F). Now for those of you thinking, "that's not that cold at all!", let me put it into perspective for you...whilst it was -20C in Tignes, in Phoenix it was 20C (68F). I miss Phoenix winters!!!!!!
