Oddy and 4X, no I don't think they need either.
G-Man, thanks for the advice. It sounds like all flights originate from KNEW and end there. I'm certain I'll be bashing a bunch of bugs on every flight!
Rag, I flew into Picayune MS a month after Katrina to drop off relief workers, and I overflew Bay St Louis and New Orleans on my return. The LUCKY ones were the ones with the blue tarps... they still had homes to return to. New Orleans was mostly flooded even a month later, and I saw entire neighborhoods at Bay St Louis a full 5 miles inland that had been completely washed away by the storm surge. Imagine a storm so powerful it could bring a 20 foot tall wall of water 5 miles inland...

Picayune MS was used by relief agencies as their center for relief and rebuilding because it was the closest city to the Gulf Coast that still had power. FYI, Picayune is 50 MILES inland! The countryside around Picayune is all Georgia Pine forest, which is planted and harvested privately for the paper mills in the area. When I descended into Picayune, I was struck by the fact that I could actually see the forest floor through the trees. Usually all you see is the pine canopy. Once I landed I realized I could see forest floor because 50-75% of the trees had either been knocked down or snapped in half by the hurricane winds.
Katrina went through Picayune as a Category 3 Hurricane, and the damage path reminded me of a 50 mile wide tornado.
Now I am guilty of thread drift! Hehe.
