Why no places for New Orleaners to go for an emergency?

Unlike before, there aint gonna be no place for people to gather, no superdome, no airport, no nowhere.. so just where are all the destitute, and stranded to go?

I saw a lot of firsthand films about just how nasty Katrina was, and despite the problems, there's a lot of folks alive now that would NOT be without those places of last resort.. so.. are the local authorities F***ing INSANE?..
I do not get it....
