Not meaning to sound morbid but what happens to the bodies buried above ground when the hurricane hits NO?! That would be freaky if they do what I think they would do!
I know what Agnes did to some of the cemetaries around here, washed some of the coffins buried up and away. That wasn't pretty. But aren't most of the above ground burials around NO done in vaults? Those might actually withstand flood waters better I would think.
