It was the end of an era on Friday night at Canoga Park High, where Mark Nogy completed his final high school football home game as the public address announcer on the 30th anniversary of his debut. He's a Canoga Park graduate who later became a school counselor and also announced Pierce College football games. Former Canoga Park principal Denny Thompson wrote on Facebook, "Mark has never been shy about telling anyone who will listen just how great the community, staff, and students are."
