The buses are all there, all in neat rows. The engines are above water and obviously they start and are driveable. The 20 year old Gibson went and got one and drove 70 people to Houston in one of them.
The mayor saved the buses at the expense of the dead.
Not all of them. On the last thread, someone posted two bus yards in NO where the buses were flooded up to their roofs, which rendered them unusable.
