It is a beautiful late August day, so the large window on the north end of the stadium is open, as is the roof.
It's like being outside. This retractable roof is an architectural feat. The two panels weigh six million pounds and cover four acres. It takes about ten minutes to open or close the roof.
This stadium was built in 2008 and has already won the chance to host the Super Bowl in 2012. That will be good for the local economy.
You are not going to see much movement in this short video, but it does go smoothly for something that weighs six million pounds! In this video you will also be able to hear the motors that move the roof sections.
