My dad was one of the Bell Telephone employees who volunteered to do infrastructure-repair work in Mississippi after Hurricane Camille hit in 1969. He was a solid photographer, and he came back with lots of color slides of the destruction. I remember seeing them years later, when I was old enough to understand what had happened. They were more eerie than harsh, probably because a lot of the phone-system repairs didn't really start until after the waters had receded and the first phases of cleanup had been finished. I remember large boats resting hundreds of yards inland, two-story houses with water-stains bisecting the second floor, and brownish swaths of flattened vegetation.
I can't imagine what it's like in New Orleans, Biloxi and Mobile right now. Cleaning up a mess is one thing. Getting caught in a mess is a different story.
