Grand Canyon Skywalk

Just seen a story on BBC News 24 about this 'Skywalk' opening at the Grand Canyon.

It has a glass floor so you can look straight down. It's a fantastic idea. I've always wanted to visit the Grand Canyon and will one day, I'm sure. I know that I would really love to walk along this as the views and perspective will no doubt be amazing. Mosh would do it without a second thought (apart from the cost, he is half Scottish after all), but I am terrified of heights.
Last week I tried to take a photo from the fifth floor balcony of the hotel I was staying in and could barely hold the camera steady and was struggling to control my breathing. And this is fairly mild for me. Usually my hands start sweating, my legs shake and and I feel unstable to the point of needing to hold on.
I froze a third of the way up on the famous flight of steep steps to the top level of Angkor Wat in Cambodia and had to be helped down.
There is no doubt I would give Skywalk a go. I am determined to not let my fear stop me at least trying.
However, I can guarantee any photo I tried to take would be blurred.
