That photo brings back many memories, as I was living on Maui at the time. Shirley was a great surf photographer, and a lovely lady.
In '76, a bunch of us Hawaii guys were in Bali. Uluwatu and all the regular areas were flat for days, so Shirley, Fast Eddie, Reno, Joanne, and I rented a VW van with driver for $20, and headed out to explore the island, looking for anything we could find.

Unfortunately, we took no surf photos that day, but I got this shot of Reno's wife with some of the ladies from the local fishing village:
Hopefully I'll find more photos from that trip ..
