Assuming the worst case scenario becomes reality, what the Saints do will be the least of the Big Easy's problems. There are thousands and thousands of people lining up to ride it out in the Superdome, and I read one article suggesting the possibility of 100 billion dollars worth of damage. Shoot, throw in the effects of more interrupted oil processing in the Gulf.
Right now that sucker is a strong cat 5, packing 175 MPH winds.That would be bad enough hitting a location that was above sea level. I can hardly fathom what it could do to a city that sits at/below sea level.
My prayers and well wishes to everyone either in the path of or with a loved one in the path of this storm.
