Many, many waiting to be rescued. A couple of hours ago the CNN cameraman that went on some rescue missions said that the estimates he heard was 500-1000. However they also were told that the area they saw was not the worst.
But you know what, they may be miserable and waiting, but they are alive, and will be rescued.
And that was in New Orleans.
I think the number will be in the multiple thousands... I hope I'm wrong.
