The buses are in the upper left portion of the image, you might have to scroll around in case you can't find them.

The mayor of New Orleans has complained that he did not have buses to evacuate his impoverished population, claimed it was the Federal Government's fault that these were not provided. HOWEVER, the city was in possession of at least 250 buses, which are now underwater.

As you can see from the image, they're polluting the water, too.
