maryjane, we live in east MS. We have tornadoes and hurricanes to deal with. Once every hundred years or so we may have a flood of catastrophic proportions. Thirty years ago we had a 'hundred year flood' - this is what the old folks called it, a flood that happens once every hundred years...don't know how they have that figured out unless they got it from the Choctaws.
The mess from a flood is NASTY. You have all sorts of water creatures get into your walls and stay trapped once the water goes down. And then they die and STINK! And the scum left from the water is almost as bad...As far as the cleanup goes, a twister might not be as bad...depends a lot of what kind of mess you prefer.
Yes, a lot of people's security has been shattered, especially the old folks. There will be a lot of opportunities for clean-up work for willing volunteers. The church shines when it comes to doing this. Come to think of it, I never heard of an atheist group coming into a disaster area and volunteer their time and resources to assist stricken folks....
