Derek asks the question that's been in the back of my mind, and I'm sure it's been in the back of other people's minds as well:

So now that New Orleans is underwater, and the devastation of property is huge, various charities have started beating the drums about raising money to "rebuild New Orleans".

I'm forced to ask myself one simple question: "Why?"

As he says, it's not as if this threat was unknown - it's been the "crazy aunt in the attic" of New Orleans for decades. It's worse than the coastal communities that get whacked from time to time, because at least the water leaves those - as bad as Biloxi was hit, for instance, it's not underwater.
