The Saints are not the only ones with a problem.
The New Orleans Bowl (http://www.neworleansbowl.com) and the Nokia Sugar Bowl (http://www.nokiasugarbowl.com) are played there too.
I suspect they may be looking for a new location for those games as well.
What's the problem?
Doubt it, the Superdome will be repaired and up and running way before the Bowl games in January.
