Yes, a structural engineer (or engineers) toured the SuperDome today and concluded that the damage is worse than first thought. He said in all likelyhood they would have to tear it down and start over. The N.O. Saints, knowing that it'll be awhile until they play in N.O. again, and that a sizeable portion of their fan base has left (or will be rather destitute and concentrating on other things when they do return) is seriously thinking of getting out. San Antonio and Los Angeles are said to be high on the list of possible new homes for the Saints.
So it's a safe bet that the Sugar Bowl will be relocated as well? Early on I had heard they hoped to play...maybe expecting the Superdome to be ready by January 1 was optimistic...although at that point there was no reason to cancel or relocate the game just yet...
