The CFN Podcast Centre has been frozen over this week in Calgary`s coldest stretch of frosty weather in two decades. It's been a week straight of temperatures between - 20 and - 30 degrees Celsius. Yes. Celsius. Apologies to the three other countries in the world that might stumble across this post via a google search who do not use the metric system. That being Liberia, Myanmar... and what was the other one again? You can take the temperature above and use this site to convert them if you wish. Sorry. The cold brings our my inner Rick Mercer and the Podcast Centre, after all, is all about the cold temperatures this week. Tune in to listen to a rant on Canadian weather.
