Sean,
Katrina was a bare shadow when you met her of what she is to be. The experts are saying she is close to surpassing Camille in intensity and if she hits New Orleans dead on she could eclipse Andrew in $ damage.
Most of my prep work is done, all that's left is screwing the plywood down - that'll get done this evening when it cools down some.
(PS, sorry about your nanners! Thank god they are a persistent plant!)
