The folks from Brine Media have made available (free!) all 12 episodes of “Silver Kings,” a series of 22-minute shows following Capt. Bou Bosso and Capt. Rob Fordyce as they compete in fly-fishing tarpon tournaments during the 2014 season in Islamorada, Florida. There’s plenty of agony and ecstasy on display, as well as some serious abuse of clients and guides. Just watching some of these scenes is stressful and/or invigorating.
