Even as a hearty Canadian, i can't help but think that temps dippin down into the negative 40 celcius range tend to be a bit on the ridiculous side. At first its sorta fun...like, 'wow its dam cold...this is so hardcore'. However, the thought tends to be fleeting and your stuck wishing for something "warmer", like a balmy -10C or -15C. Whatever...it's cold and that's the way it is. Keep at it with the skis and dream about pealing surf that doesn't involve your feet feeling like frozen stumps.
