A cheeky question, I know, but business colleagues in Calgary had a stock answer to when summer might appear. I never did visit Calgary in summer, but one week in mid winter the temperature reached -30°. I used to walk across downtown in the early morning from hotel to office. If the temperature was below -10°c, icicles would form in my nostrils!
My wife noted that pedestrians mainly passed each other on the sidewalks by the rule of the road, that is to the right of each other. Given the often icy conditions that made a lot of sense.
17 years ago we celebrated my 60th birthday at Banff Springs Hotel, what a magnificent place. Great memories.
