A retired nurse, her son, and a family friend say they were lucky to survive last week's flash floods in Texas that killed more than 100 people, including many summer campers.

Whitney Slough said her husband and their two daughters were snorkeling about 20 feet from the beach when a small boat appeared along the shoreline.

Residents are clinging to hope as the search continues for Mark and Sara Walker and their 14-year-old son Johnny.

Clara and Nolan Shelton shared their experience of when their summer camps, overtaken by the deadly flash flooding.
