Where do you live? And yes, you should if it's not called a weather disaster then you should go! Here last year on February it was -57?C and I went to school, not to mention it takes me 40 minutes to my school when it's sunny... So how bad is the temperature?
Stay home, humans are not meant to be risking snap freezing in such frigid weather. I do not understand the pack mentaility here that scoffs and jibes at people making sensible safety decisions. Thank goodness its only a few squeaks from the billions that make up all people. Its irrelevant what others choose to do, and my kids would be staying home FOR SURE.
