At the back end of the line, people jammed against police barricades in the rain. Refugees passed out and had to be lifted hand-over-hand overhead to medics. Pets were not allowed on the bus, and when a police officer confiscated a little boy's dog, the child cried until he vomited. "Snowball, snowball," he cried.
The scene played out Thursday as the plodding procession out of the Superdome entered its second day — an evacuation that became more complicated as thousands more storm victims showed up at the arena.
CBS News Correspondent John Roberts reports that the Superdome evacuation had to be suspended after several people demanded rides out of town at gunpoint.
Capt. John Pollard of the Texas Air Force National Guard said 20,000 people were in the dome when the evacuation efforts began. By Thursday afternoon, the number had swelled to about 30,000. Pollard said people poured into the Superdome because they believe it's the best place to get a ride out of town.
The refugees began arriving Thursday at the Astrodome in Houston, where they got a shower, a hot meal and a cool place to sleep.
"I would rather have been in jail," Janice Jones said in obvious relief at being out of the dome. "I've been in there seven days and I haven't had a bath. They treated us like animals. Everybody is scared."
Miranda Jones, her daughter, was standing next to her, carrying her father's ashes — the only thing they were able to save from her house before Hurricane Katrina blasted New Orleans.
An angry Terry Ebbert, head of New Orleans' emergency operations, watched the slow exodus from the Superdome on Thursday morning and said the Federal Emergency Management Agency response was inadequate. The chaos at the nearby New Orleans Convention Center was considerably worse than the Superdome, with an angry mob growing increasingly violent and few options for refugees to leave the scene.
"This is a national disgrace. FEMA has been here three days, yet there is no command and control," Ebbert said. "We can send massive amounts of aid to tsunami victims, but we can't bail out the city of New Orleans."
After a day in line in the heat without water or food, dozens of people fell out. Medics poured water on them, fanned them, and tried to cool them down.
One woman, lying on a canvas cot, was in convulsions. Medics doused her with water and slapped her, trying to bring her around. A National Guardsman poured water on a baby he held while water was also poured on her mother.
The tile floor got wetter and wetter, and some people slipped and fell.
Meanwhile the crowd kept growing as stranded people heard about the buses and headed to the dome.
By early afternoon, a line of people a half-mile long snaked from the Superdome through the nearby Hyatt Regency Hotel, then to where buses waited. State troopers, making every effort to be cheerful, handed out bottles of water and tried to keep families and groups together.
"I need three," a burly state trooper called out. "I need four."
At one point, the guards held up the line so a young teen at the front could go get her sister, farther back.
