Nathan Day was up early helping his son get ready for work when he received a message from a neighbor asking him to save her grandchildren from the rising floodwaters.
Day, a former coal miner who lives in Hindman, Knott County, said he was unaware of what was happening in the region until he received the message saying the children needed help getting out of their house. Day talks to Anderson Cooper about how he managed to rescue 5 children and 2 of his former school teachers from floodwaters without a boat or proper equipment.
