I am always the most impressed with the grass. The Arizona Cardinals' football field is quite unique. What's so special about grass? Well, University of Phoenix Stadium has the first fully retractable natural grass playing field in North America. That means that the grass is outside, getting natural light until a few days before game time and then it is rolled into the stadium for the game. It is quite a marvel of engineering and ingenuity! What kind of grass is it? How does it roll into the stadium? How long does it take? I'm not telling. You'll have to take the tour!
When there's no grass on the inside, University of Phoenix Stadium also hosts trade shows and events, such as Kidsfaire, the West Valley Home & Garden Show, the International Sportsmen's Expo, and the Fiesta Bowl National Band Championship.
University of Phoenix Stadium Tour Tip: Wear comfortable shoes. You'll be walking about a mile on this tour.
