Why not use New Orleans' buses?

Over at Huff Puff they are making a big deal out of a Wall Street Journal article:

FEMA Requested Only 455 Buses To Rescue 20,000... Then Canceled Order And Took Until Sat. After Storm To Send Enough Buses...

As the director of the Federal Emergency Management Agency stepped down yesterday, government documents surfaced showing that vital resources, such as buses and environmental health specialists, weren't deployed to the Gulf region for several days, even after federal officials seized control of Hurricane Katrina relief efforts.
...
In addition, FEMA's official requests, known as tasking assignments and used by the agency to demand help from other government agencies, show that it first asked the Department of Transportation to look for buses to help evacuate the more than 20,000 people who had taken refuge at the Superdome in New Orleans at 1:45 a.m. on Aug. 31. At the time, it only asked for 455 buses and 300 ambulances for the enormous task. Almost 18 hours later, it canceled the request for the ambulances because it turned out, as one FEMA employee put it, "the DOT doesn't do ambulances."

FEMA ended up modifying the number of buses it thought it needed to get the job done, until it settled on a final request of 1,355 buses at 8:05 p.m. on Sept. 3. The buses, though, trickled into New Orleans, with only a dozen or so arriving on the first day.

I guess the people at Huff Puff are so wrapped up in their little, Liberal universe that they haven't heard about these buses that Ray Nagin could have and should have used to do just what they are complaining FEMA didn't. Oh, and it was his responsibility according to the NO Emergency Plan, not FEMA's.
