My brother, Jon, trying to look tough, while hubby Dan trying not to hurl from the height. This is from the "Crystal Bridge" from the Myriad OK Botanical gardens conservatory. It is 224 feet long, 70 feet wide and a jungle paradise. It is made of seventeen tricord trusses which form the frame and 3,208 panes of Exolite acrylic which form the shell. These crystal clear, double-walled panes insulate the Conservatory's coolers to ensure a healthy and stable growing environment. They also protect the plants from the harsh winter climate while greatly reducing heating costs. This entire bridge where Jon and Dan are standing is actually suspended over a large pond, so these guys are not just towering over me and the jungle, they are also suspended over a large lake as well. Which is why Dan looks a little pekid.
