Mystery photo, Martin Aviation, John Elliott, etc

Today's Orange County "mystery photo" seems like it should be easy to identify. But all I know is that it hails from November 1964 and that it originally came from the County Planning Dept. Perhaps you'll recognize the spot or at least have some educated guesses.

The folks at John Wayne Airport tell me that Martin Aviation will open an aviation museum on the west side of the airfield in August. Does anyone out there know more about this?

The Santa Ana History Room at the Santa Ana Public Library has a new guy at the helm: John Elliott. Actually, he's been in charge of the collection for several months (and has worked at SAPL for much longer), but I only got the chance to meet him today. He seems extremely well-suited to the job, and I think he'll be a great asset to the local historical community. Welcome to the wonderful world of O.C. history, John!

After 105 years, the Fullerton Women's Club was down to five members, and the youngest was 79 years old. Plans were being made to close up shop. But interest picked up after Dave Lopez of Channel 9 News covered the story, and now they claim they are "going strong again." You can see Lopez' report on YouTube. (Yes, I know I'm reporting this story a little late.)
