We went up the Calgary tower the other day, I have only been up there one other time, it's been years. The kids thought the glass floor was awesome and didn't even bat an eye about going on it... me NOPE! I could not do it.. I wanted to and tried, just couldn't do it. it was a clear beautiful day and could see for miles! what a beautiful city we have! We might just have to do this a little more often.
