some of NOLA won't get rebuilt.
People will not wait 6 months to start to build another house. Some of those with skills will move their family, find a job.
It's an individual decision.
WWL interviewed by phone two NO policemen who had evacuated to Dallas, one on Saturday (he was already injured and left with his family before the storm), and his brother, who had stayed in NO until yesterday. The one who stayed until yesterday said they had no support, no leadership, and it was every man for himself trying to do whatever the police were supposed to do. The news anchor asked later in the interview when they were planning on coming back to NO, and one said, "We're staying here. This is our new home. We're from Texas now."
