I used to live in Calgary, and while I was there it got down to -46 C (or minus 51 American) (not counting wind chill) one week... My buddies still living there told me that this past wednesday including the wind chill it got down to -58C (or minus 72 American)... That is freakishly cold!
Here in Oklahoma, its been a balmy 33ish all day... and a north wind blowing, so we should see some new ducks tomorrow morning!
