Glad to read an update on Don. I first became aware of his personal work in 1970 when we were asked to exhibit at the original Friends of Photography Gallery in Carmel. It was a three man show including Ed Putzar.
A few years later I started doing freelance work for Sunset Magazine and saw Don's photography in every issue. As you note, it was quite a different magazine back then when Proctor Melquist was editor.
I hope Don is doing well.
