We saw in Hurricane Katrina that they had just (ended) a year and a half of focused planning on dealing with that exact scenario, and they fell on their face. So just to say you have a plan on the shelf or a plan in place is not the final answer. You've got to exercise it. And if you don't exercise it and work the bugs out, Mother Nature is going to exercise it for you. And that's definitely not where you want to test your plan.
