I will tell you in all sincerity that that simply is not true. I'm pinging Burbankkarl to this because he knows how to link pictures and I don't. He has posted several pictures showing water and food at the Convention Center well before Friday.
Bottom line.....there should have been a fast response group that can respond with spot relief of food and water on a 4 hour max. basis to any gathering of survivors as they are discovered. I saw the sand bags being dropped on thursday on, of course important work. But those crews should have insured people weren't dying of thirst, first.....
