This post is over a year old but I just found it.
Here's an excerpt:
To those not acquainted with New Orleans:
Yes, we realize that much of our city was built below sea level. It's kind of the first thing you learn in school. Right after that bit about that George guy and the cherry tree and right before eating paste is bad for you.
Yes, we realize our geography leaves us more vulnerable to flooding. We don't know this because we are smart. We know this because it rains a lot and we get off of school.
Yes, we tried to protect ourselves from it.
Yes, it has worked in the past with varying degrees of success.
No, it did not work this time.
