We had breakfast downtown at the top of one of their tallest buildings, it looks much like the Seattle Needle. The restaurant rotated while we ate giving us a great view of the entire city. After breakfast we went up to the observation deck and found that, like Chicago,  there is a glass floor. We are not daredevils, but we were there, so we both walked out on the glass floor and looked down to the street where the opening parade for the Calgary Stampede Chuck Wagon Races was taking place. The horses looked like small dots!
