The photo above shows the groundbreaking for one of a couple additions that have been made to the cabin over the decades. It appears to be sometime in the 1960s.
The photo below shows some of the members with their catches at Newport Harbor on August 11, 1947. They've just gotten off the Lorna Pat or the Lorna Pat II, day fishing boats that were operated by J.H. "Bert" Mills. I'm admiring how empty the San Joaquin Hills are in the distance behind them.
