It sure would make one helluva rink, right? From its Wiki:
Cowboys Stadium is a domed stadium with a retractable roof in Arlington, Texas, for the National Football League's Dallas Cowboys. It replaced the open-air Texas Stadium, which opened in 1971, as the Cowboys' home. It was completed on May 29, 2009 and seats 80,000, but is expandable to seat up to 111,000.Tickets would have to be quite cheap to get over 100,000 people to pay to watch the Stars but still, what a sight that could be. Maybe they should keep the Winter Classic up north but what about something special? I know the All-Star Game was in Dallas in 2007 so it isn't due to come again anytime soon but - should the NHL bail out from the Olympics and should they revive the World Cup of Hockey - Cowboys Stadium would make for a mighty host for the final game ... What do you think?
The stadium is the largest domed stadium in the world, has the world's largest column-free interior, and the largest video screen hung from 20 yard line to 20 yard line. [9] The facility can also be used for a variety of other activities outside of its main purpose (professional football).
