A week's supplies won't cut it in a disaster on the scale of New Orleans except to keep you alive until and during evacuation.
I have to laugh a little at the eager assertions on the part of the east-coast Dems that it's Bush's fault for not sending more tax money to build up the levees. When your arm's been amputated bandaids don't help.
They do realize that Reconstruction is all over and Louisiana now has its OWN state Govt right?
