You may have seen this already, but this guy has an interesting blog and context for his blog. A New Orleans info company has been running on generator and diesel fuel, with webcams out the window, talking about what’s going on down there.
This webcam link from his blog just showed several yellow school buses , one after the other , moving down the street (1045 am CST)
I just pinpointed the location of their webcam using Google Earth:
