The Polar Bear Plungers at Rockaway Beach today reminded me of the great Lou Harris, who teaches local youth how to swim and surf there. I am proud to present “The Sea Changer,” a documentary short directed by Oliver Gruber which I produced. You’ll be able to see more of Lou Harris on “Survivor” starting in February, as the riveting show’s executive producers Mark Burnett and Jeff Probst have wisely selected Lou to be a contestant.
