If you bleeding hearts have never worked in a disaster area you can't possibly imagine how difficult it is to move convoys of heavy equipment through it. It's nothing like taking a Sunday drive into the country for a picnic.
Relief convoys heading to New Orleans had to move through two states devasted by a category 4 hurricane. Not only were many of the highways covered with debris that had to be cleared, but all the power was out, making it almost impossible to refuel the relief vehicles. The convoys had to bring every drop of fuel they needed with them.
For several days after the hurricane passed the only access to many communities along the coast was by helicopter.
Under those circumstances, I'd say two or three days to make the journey, in force, would be just about right.
I wonder what effect the complaining and tirades by Nagin and Blanco had on the overall relief efforts. Considering the extent of the disaster, FEMA had probably planned a broad-based effort to reach as many of the victims in southern Louisiana and Mississippi as possible. I suspect that Nagin's complaints and "racist" rant changed all that, guaranteeing that the feds HAD to make a maximum effort to reach NO as rapidly as possible...to the detriment of the victims in southern Mississippi.
You wouldn't know it by listening to the news media, but Mississippi was hit harder than Louisiana. Wonder what southern Mississippian's think about Nagin's asinine rant?
