Burnaby

I drove to Burnaby yesterday afternoon. Burnaby is a small city located in the east of Vancouver. It was only a thirty-minute drive from my apartment in Downtown, but the scenery was quite different out there. It was a silver city still covered with heavy snow. I was surprised to find that only a distance of thirty-minute drive to inland changes the world so much. Some of my friends in Vancouver often say that it is very cold this winter, but I don't think so. I've understood the reason; all of them are living in Burnaby or in the more eastern area. The sea water works as a heater in winter season though it looks cold, and the heat from the heater decreases in inverse proportion to the square of the distance from the sea. Plus, we can't forget the influence of the altitude. Burnaby is mostly on the hill top though it is not so high. If the temperature is decreasing in this rate, how cold is it in the inland area of Canada?
