rescuers who were pulling people from flooded homes you wouldn't believe the dev. these were neighborhoods where the water was almost to the roofs. people were waiting on rooftops and on the hoods and on the tops of their cars while water was right below them, waiting there for a couple of days. they said they had called and tried to get the city and others to come. we know how overwhelmed the first responders are. they were thinking nobody would come and the water was still rising. so it is still a very dire situation out there tonight, don. what the harris county sheriff's office has put out there to some of the people in these neighborhoods, they're saying to them, display a prominently in your windows towels and sheets so that we know that's a place where we need to come into. don't just call and give us your address because these addresses are almost unrecognizable. you've got to display towels and sheets prominently your windows.
