You didn't read what I wrote. It was a dumptruck with at least two pallet loads of water bottles in its bed. Interestingly, later Shepard was describing the "chaos and absolute lack of help or support" as three large, air conditioned motor coaches full of people from the stadium rolled away behind him. So you can babble on about "political websites" et al, but unless you can only hear Sheppard and not see what is going on around him, I guess I can't understand your comments.
Um, yeah, I saw that dumptruck, too. It went to the Superdome, not the freeway where so many other refugees were with Shep. Those buses didn't stop and pick up any of those refugees on the freeway. There is some question as to whether they are letting those wandering in through the water into the superdome. Shep's criticism wasn't about how the dome, it was about the total lack of info or direction given to the masses streaming all day onto and down the freeway.
BTW, the only criticism I have of the Superdome is the lack of communication, which it sounds like may have ended today. It wasn't perfect, but it was better than the alternatives, and was a wide decision to use as a 'refuge of last resort.' It is only a temporary shelter, and has performed as intended.
