Let me clarify something, the few storms that I have evacuated from have been small ones that affected much smaller areas than Katrina and Rita. For those events, my method worked fine.

Because of Katrina and Rita, local/state govt's, IMHO, will now call for evacuations of coastal areas, than those areas just inland, and finally those low lying areas farther inland. I don't think that the govt's involved will put off the decision making as long as they have tended to in the past. If anything, they are going to call for evacuations earlier (probably too early) and no doubt needlessly, for some areas. This means that large scale public evacuations on the Katrina/Rita scales are going to be more frequent.

Some of the areas that haven't been addressed, as I see it:
1) Gas stations along Evacuation Routes are not being required (new construction) to have larger gasoline/diesel storage capacity.

2) Shelter supplies are not being procured and pre-positioned in sufficient quantities.

3)Shelter supplies that have been procured and pre-positioned are not being adequately stored under the proper storage conditions.

4) I'm not seeing any pre-hurricane/evacuation public education campaign being conducted except to maybe small groups here and there.

The lessons that all of us here, and a few PHRASECENSOREDPOSTERSHOULDKNOWBETTER. around the country, have always known or recently learned are:
1) You will wait a long, dry, hungry, and insecure time waiting for any level of govt to arrive to bail you out of the situation you've allowed yourself to be in.

2) "Just in Time delivery" doesn't work well in evacuation situations.

3) The govt's advice about having 72 hours of supplies on hand is BUNK! I know that because on those same web pages, they also then advise people to have more than that in order to be "properly prepared".

4) I am reminded that these are the same people who brought us the Vietnam War, a socialized welfare dependant system, Crime safety through Gun Control, etc, etc...
