I tried to add a couple of photos taken weeks after the storm, but I need to do a bit more reading to get the voodoo.
What the pics would have shown were the number of vehicles strewn among the devastated areas, specifically the predominately black neighborhoods. In the areas that had a different racial balance there are hardly any. What I devine from this is that while the ability to flee was there, the industry to do so was not.
Unfortunately it seemed as though the elements of the population that are notorious for not following the advice of the authorities and for relying on others to assist them in making their way through life did just what should have been expected....nothing, Just sat on their prettythanges and waited for someone to carry the load for them.
As a native to the coast I can tell you that it's a real hardship for many to evacuate. Traffic, accommodations, provisions can be the least of your problems when you've got tight finances and are worried about what would happen to your property once abandoned. Assuming you have assets worth protecting.
And the idea of citizens commandeering those school buses for some kind of "grass roots" evac caravan is just stupid on so many levels that it would require another thread to adequately discuss.
And don't forget, New Orleans survived the storm, it was the under engineered levees and the mismanagement of parish officials that caused the flood. I doubt any one out there would have foreseen that although in hind sight it did seem pretty inevitable.
