Last year, the Hulk; this year, Ponch. The Boys & Girls Club of Bulloch County has announced that Erik Estrada, best known for his role as motorcycle cop Frank Poncherello on the 1977-83 TV series “CHiPs,” will speak at the club’s annual fundraising gala, Sept. 7. Lou Ferrigno, who made his greenest mark as the title hero in the 1978-82 series “The Incredible Hulk,” but who, like Estrada, has continued a long and varied career in TV in movies, spoke at last year’s 11th annual Steak & Burger Dinner.
