My wife emailed me this image, wondering if it was real. Yes, it's real. I think it's been circulating around for a while. It's one of those once-in-a-blue-moon kind of emails in which all the information is actually correct:

New Grand Canyon Sky walk
* Scheduled to open Jan. 1, 2006 Hualapai Indian Reservation
* Juts about 70 feet into the canyon, 4000 ft above the Colorado River
* Will accommodate 120 people comfortably
* Built with more than a million pounds of steel beams, and includes dampeners that minimize the structure's vibration.
* Designed to hold 72 million pounds, withstand an 8.0 magnitude earthquake 50 miles away, and withstand winds in excess of 100 mph
* The walkway has a glass bottom and sides...four inches thick

A hi-res version of the image (which is a drawing, not a photograph) can be found at destinationgrandcanyon.com. I'm not sure I could go on this skywalk. I don't consider myself afraid of heights, but the last time I was at the Grand Canyon I had a lot of trouble getting too close to the edge without feeling sick to my stomach.
