Next, Gayle travels to Baton Rouge, Louisiana. "They tell us that the population in this town has doubled to 800,000. That's because people pouring in from New Orleans are looking for a safe place to stay," says Gayle.

One survivor, desperate to help, admits to "commandeering" a boat in order to rescue stranded residents.

Survivor: A friend of mine was stuck in New Orleans in the flood, and they [were] running out of food and water, and they needed some help. … I drove down to New Orleans [and] we commandeered some boats.

Gayle: What does commandeered some boats mean?

Survivor: We stole some boats—18 boats—and we rescued 300 people.

Gayle: Wow! Were you afraid, or did you just say, 'I'm gonna do something'.

Survivor: I just had to do it.
