mis, edgar, mac, and anyone else in the potential path of this or any future storm... be well, be safe.
Bill, I'm agreeing here with you, squinney, and rockhead that folks choose where to live and that nature does what nature will do. Saying that Mr and Mrs Jones (if by that you mean you and me as taxpayers), who are responsible for much of the current reality in certain areas, should get to call for the bulldozers when they were wrong to begin with and displace hundreds of thousands of people (New Orleans is currently at 75% of the pre-Katrina population of over 400,000 people) is simply wrong.
No one in the delta that I know, and I know many, think government intervention is a viable answer. There are numerous grass-route efforts to reclaim the delta and the natural barriers that it provided. Katrina was a disaster that took it's toll on millions of people across many of the gulf states. Most of the fatalities in New Orleans were due to the break in the levies, not to hurricane force winds. Natural disasters have, and will, take additional tolls. Mr and Mrs Jones don't get to shrug and say better luck next time.
Everyone chooses where they live. Sometimes Mr and Mrs Jones are a detriment to that choice. Once Mr and Mrs Jones have screwed up, they don't get to say that those in the fallout should be displaced.
