It all began 56 years ago when elated members of the Old Mission Beach Athletic Club (OMBAC) celebrated the return of Delmar Miller, who had been a prisoner of war during the Korean War. The festive occasion continues as OMBAC prepares for another huge, fun-loving Coming Out Party at Mariner’s Point across from the Bahia Hotel on Saturday, May 14.  Miller will return this year as the honored guest. “It all started after Miller, one of our founding members, had been released from the prisoner of war camp,” said Brad Pagano, publicity chairman.  “When he got back, it all escalated from a small gathering of friends into this big party, and it also became the official kickoff to the summer here.”   The festive beach gathering runs from noon to 10 p.m.  As an added attraction, a Miss Mission Beach contest will be held. The featured bands will be Bad Seeds, Days of the New Dawn, Boomsnap, Splitfinger, Jetwest and RX Bandits — part of 13 musical groups on two stages. “The major purpose of the party is to be a fundraiser for the many charities OMBAC supports,” Pagano said.   Tickets are $15 in advance and $20 at the gate. He said OMBAC supports wounded veterans, local youth charities, the American Cancer Society, the Armed Services YMCA, the San Diego Sports Association, police and firefighters. “Of course, the Over the Line tournament (in July) is OMBAC’s main event,” Pagano added.
