These are the school buses at McBride School in Plaquemines Parish - notice how they've been thrown into a sort of a circle while others are in the trees. Parish authorities related on WWL how they were evacuating their fire trucks because 'those things are expensive to replace.' Evidently school buses are cheap. Buses are in the top center of the image.

This would be Sonrise School, also in the Plaquemines parish. The buses are in the bottom left hand side of the image.

There are more places - I remember seeing one place that had loads of short buses that were flooded out too, but to be honest, I can't go through that NOAA imagary anymore tonight - Plaquemains parish is a horrible place to look at from above.
