Looks like the beach at El Segundo in Southern California.
When Bryan and I worked for a division of the Xerox Palo Alto Research Center,
we used to eat our bag lunches at that beach. I know that your pic probably isn’t
on the West Coast, but it did bring back memories.
We were both RA-5s and we made pretty good money until the PTB up in Menlo
Park decided to close the Advanced Development Lab. Our boss took us to a new
company, where we used our expertise to good end, so we three landed on our feet.
