One aspect of Katrina that has really disturbed me has been the lack of news from parishes further down the Mississippi delta in Louisiana like Plaquemines Parish and St. Bernard Parish. Many of the people who live down in the bayou never evacuate, and they must have faced the full brunt of the storm surge. I finally saw some pictures posted by the Plaquemines Parish government, and things are looking as bad as I had feared.
Update: As you probably discovered, the Web site linked above was down for much of the afternoon because of bandwidth overages. It seems the problem has since been rectified.
