Hhhhhmmmm. I've been watching news coverage of this disaster closely, and I've seen an awful lot of flooded vehicles - sitting in people's driveways.
That's what I've been saying all along. Those vehicles and their owners shouldn't have been there--they should have been on the way out of town. Many of the people who got stuck in NO got stuck because they wouldn't take the warnings they were given and use their own resources to get out of town with the rest of the NO residents. That's just made caring for and evacuating those who really need government help far harder and the lives of the most needy and helpless that much more difficult.
