I just checked MapQuest and it's about a 25 mile walk from New Orleans to Carlisle.
Did any people just walk out of the city after the flood and find someone in a city or town further north with some compassion and help get their lives started again?
That's what I think I would have done with my family, given the situation I see.
That would have been the normal thing to do! These are not normal people.........
That was my reaction, too. This doesn't seem to be normal problem solving behavior. Walking as far as you can from a disaster area is just human instinct. I would have started walking toward any incoming traffic. If nothing else, it would relieve the feeling of sheer boredom and frustration. At least I'd feel like I was doing something. I would also think any supply trucks would offer food to those people it would see first. Relief workers might resist giving an inadequate supply to the masses to prevent rioting, but perhaps they'd be able to help smaller groups or individual families.
