This panorama captures the Arizona Cardinals on game day at State Farm Stadium. With its exterior skin representing the indigenous barrel cactus, it was the first stadium built in North America with both a retractable roof and a retractable field. The field weighs 18.9 million pounds and is moved in only for game days. The Cardinals are the oldest existing professional football club in the United States and are a charter member of the National Football League. Since beginning play at the venue in 2006, the Cardinals have sold out every game played at the world-class venue and their fans helped to create one of the best home-field advantages in the National Football League. 2
