Just a warning, for those who are going to Calgary. This morning, it is snowing, and the forecast for the weekend is for highs around 45F (7C), with lows around freezing, so dress appropriately.
The forecasts usually change, day by day, but I doubt if it will change a lot. Then again, Calgary has been known to be at -40F (-40C) at 08:00, and 40F (7C) at 16:00, but that is usually in January.
