Superbowl 42 will be played in Glendale, Arizona this Sunday Feb. 3rd at the University of Phoenix stadium that just opened in August of 2006. We visit this 455-million dollar facility and take a closer look inside: It's the first stadium in North America to feature a retractable roof and a roll-out grass field. It's all part of a huge development in Glendale, in what used to be cotton fields just six years ago.
