The last (and only) UFC event held in a Stadium was 129, and we missed out on 148 which was supposed to be a Soccer stadium in Brazil (would have been HECTIC!) but was moved to the MGM Grand. There was just an enourmous vibe in the room at UFC 129, where the fighters tried that little harder to impress the 55,000 spectators (human psychology, right?) and the energy in the cage must have been unreal! In the US, there are so many Football/Baseball Stadiums, In the UK, Brazil and Europe there are so many Soccer stadiums! And the same in Asia too. Imagine Londons Olympic Stadium or Wembley Stadium Wembley Stadium FULL I mean who saw the Opening and Closing Ceremonies to the Olympics?!
