I don't know about you, but this storm may well be the worst natural disaster to hit the USA - ever.

From CNN:
"Shelters have been set up at 10 sites, including the Superdome, for people who cannot leave the city for medical or other reasons, but Nagin said they should be used only as a "last resort." (See video from New Orleans, where not all are ready to leave)

He said people who must stay in the shelter should bring enough food, water and supplies to last several days."

"Nagin said the storm surge would likely topple the levy system that protects the city."

There's almost nowhere in New Orleans that won't be underwater - this is a city of about 440 thousand people. I can't think of anything that compares.

This is NOT a shelter-in-place situation.
