Actually I am in Alberta as well, central Alberta.
Today and for the last few days it has been around -1 celcius, thats about -100 to -200 farenheit.
And we are wearing T-shirts and sun glasses. Its been really nice for a while now.
In the summers we see +30 celcius give or take 5 degrees. In the winters it can get down to -40 on a bad day, but usually right around the -10 to -20 mark. (Celcius of course).
And the witches mammaries that I have measured were quite cozy.
