I hope I did not come across as completely dumping on your thought because, believe me, I was thinking the same thing. Why make the same mistake twice? That piece of sod on which the city of New Orleans was built is seemingly the worst place you could imagine to put a city. But then I started cranking into my nerdy legal analysis... lol.
Good sense would dictate that rebuilding is a mistake... I just keep wondering what the alternative truly is.
