The teams took time on the day before the Super Bowl to walk through NRG Stadium and check out where they will play the big game.
Meanwhile, security is being ramped up. Houston Police Chief Art Acevedo says much of the security in and around NRG Stadium will take place quietly behind the scenes. One possible exception will be the Black Hawk helicopters being used to monitor restricted airspace over the downtown area. NORAD fighter jets will also be on alert in case a plane needs to be intercepted on game day.
