The Grand Canyon Skywalk:
4000 feet above the Coloroado river with a clear floor!!
I wonder if they'd let us roll our Monsters out there for a picture??
Pretty impressive build!!
I watched a Discovery special about it. It's strong enough to support the equivalent weight of 71 loaded 747 airliners or an 8.0 earthquake within 50 miles!!
Although I doubt they'd let any of us yahoos roll our bikes out there for a pic, every visitor has to wear medical style shoe covers to walk the glass. Then again maybe if DNA organized the shoot??!!
