I don't think the squirrel was the only one wishing spring would arrive (amazing amount of upside down/stuck cars on the way into Edmonton).
At temperatures below -20, you'd get some pretty interesting and annoying phenomena. Mucus in your nose freezes, tripod joints freeze up and on a couple nights there was this weird ice fog that created neat pillars of light above streetlights, kinda like these;
