So I was born in a small mining couminity north west from Dawson City, Yk, in 1978 in may. My grandparents came to visit that Christmas and we had moved to Whitehorse as the mine had closed. The temperature reported by the Whitehorse airport was without windchill -67°c. This is something that my father confirmed with the outdoor thermometer. Whitehorse Yukon Territory Canada. . . . Granted in 78 record keeping was. . . Questionable.
