Ken,
This is what I found when I searched for New Orleans Hurricane plans.
When I searched the document, it mentioned city transit busses, but I
couldn't find a reference to the words "school" or "school bus" in the
document. If you do find that other link, please send it along.

An unreasonable man (but my wife says that's redundant!)
The reasonable man adapts himself to the world; the unreasonable one
persists in trying to adapt the world to himself. Therefore, all
progress depends on the unreasonable man.
-George Bernard Shaw 1856-1950
