Depends what you want to know! lol. I live in Calgary so feel free to PM me with any questions or ask on here. As far as weather goes... Could be upper 90's one day and pouring rain the next. One never knows with Calgary
Well if the dollar stays good (for you guys) then spending money will be at a great exchange rate.
Visit the Calgary Stampede website, lots and I mean LOTS go on during that week. If you want to get out of Calgary I'd suggest checking out Spruce Meadows and taking a drive to Banff OR going down the Cowboy Trail.
Weather.....well even us from Alberta can never predict what will happen
