Grand Canyon Skywalk: As if the experience of the Grand Canyon is not breath-taking enough, this new tourist attraction lets you walk out over top of the Canyon via this walkway. The Skywalk is a glass bridge that is suspended 4,000 feet above the Colorado River over the Grand Canyon. The tech specs for the bridge are amazing: it is strong enough to hold a 747 and can withstand up to a 8.0 earthquake! Check out the site for more info and pictures.
Would you walk out on this bridge? Would it freak you out?
