The Big Easy, Naptown or the Twin Cities. That's the choice facing NFL owners when they vote Tuesday, May 20, 2014, on the site of the next Super Bowl, choosing between New Orleans, Indianapolis and Minneapolis. Each city has hosted the big game, albeit just once for Indy and Minny. (AP Photo/Gene Puskar, File)
