The "Where are they now?" file

What ever happened to all those New Orleans residents who evacuated before Katrina came ashore? Most of them were black, but "racism" doesn't seem to have robbed them of the means or the foresight to get out while they could. It wasn't "the black population of New Orleans" that stayed behind; it was a fraction of the black population of New Orleans along with a fraction of the white population of New Orleans.

What happened to the majority who bugged out? How are they doing now? Where are they staying? It's as if they simply vanished.
