From this comes this completely unconfirmed, short, second-hand story:
Last night I met up with a friend from New Orleans that had stayed behind because he had been told that the I-10E was closed. He met with a couple of friends and hoped for the best while hiding out in a local hospital. Boats came and pulled people out of the hospital and dropped them off at an intersection where they just waited and waited. Finally a bus pulled up and took them to the Convention Center, where apparently they had no security and they checked no one for weapons. It was so unruly that the cops left each day at sundown. Kent slept on the sidewalk out front with 20 others because if they went inside they would be followed and continuously threatened. Each time they tried to walk away they were followed by gangs of people who threatened to follow them or kill them if they left them behind. So they stayed...
The friend is supposedly a photog, but he was forced to leave his camera and laptop behind when he was surreptitiously rescued. I'll try to get the full story from the friend.
