Shiver, I can't even imagine what that feels like. In England, even up here in the north, it rarely gets below -5 and that's a rare event. Spring is definitely beginning here, I have started seeds in my little greenhouse and am keeping my fingers crossed we don't have a sudden cold spell. A couple of years ago all the blossom trees were damaged by a late frost (one of the very cold ones) and some have still not recovered.
