Canada’s political leaders were decked out in cowboy hats yesterday for the Stampede Parade through downtown Calgary. Local dignitaries like Premier Notely and Mayor Naheed Nenshi rode horses in the parade. An estimated 200,000 people watched the parade which begins the Stampede. It lasts until July 12, 2015. Some 700 horses and 4,000 people participated variously in the parade, which was led by a hometown girl, two-time Olympic gold medalist and bobsledder Kaillie Humphries.
