During the summer of 2011, Dave Mull spent nearly 4 hours adrift and alone in the rolling waves of Lake Michigan, clinging only to the handles of a Coleman cooler. The boat Dave had been fishing in had suddenly capsized and sank 5 miles offshore, forcing him and his three companions into the deep, troubled waters. Before Dave became separated from the others, he selflessly surrendered his life jacket to one of his friends who was struggling to hang on to the floating cooler.
