The craziest roof in Texas, according to Gizmodo, is the one in Cowboy Stadium. Here's why: it's "supported by two 17- x 35-foot arch box trusses spanning 1,225 feet. Its 14,100-ton structural steel skeleton (that's 282 Fin Whales or 92 Boeing 777s worth) is covered with a weather-resistant PVC membrane on its non-moving sections. Its movable bits, however, are what set it apart from lesser retractable-roof stadiums." And there's more. [Gizmodo]
