we've done face-to-face shelters, we went to the downtown convention center and walked around. think about going to a football game or a baseball game. you're looking for one person and you need to see them all and 20% of them are laying down covered with a red cross blanket. how can you find the person that won't call, because they don't have any information. and there's thousands and thousands of people like that. >> this is a nightmare. there's no question about it. and we keep hearing similar stories. the good news is, we also keep hearing about people getting reconnected. and we're putting it now on cnn. the picture of your father. you've said the location of where he was. if anybody has any information about this 88-year-old man, his name is harrison allen, doesn't have a cell phone. please, come to us on social media. you know how to get me. give us information if it's been there, so we can contact you. and get you in contact with his son, bradley. is there anything else we need to know?
