I think part of the problem is that so many of the people in that area are new residents with no hurricane experience.
I think part of the problem is people living in a fantasy world...
I was watching the CBS national coverage in Houston, and what absolutely infuriated me was a conversation the reporter had with this older gentleman. When asked why he was not leaving the area, he went to the old curmudgeon card and stated "Well, I'm 70 years old", like that gives him license to be a dumbass and potentially risk the lives of rescuers who might have to come an rescue him or retrieve his body after the storm is done. Irresponsibility broadcast for all the world to see.
Proven today, I am sure.
