Grand Canyon Skywalk
A new project is sure to attract some world wide attention. The Grand Canyon Skywalk (http://www.grandcanyonskywalk.com/) is currently being constructed. The skywalk is a horseshoe shaped viewing platform with a steel frame and glass all around it.
This won't be for the faint of heart, standing out 4000 ft above the ground.
The skywalk will be opened during the forth quarter of this year (at least thats the plan).
