Many decades ago when I used to travel, on one of my trips to South Africa, we saw many birds. There was a small bookstore. I think it was at one of the hotels where we stayed, with a book on South African birds. There was only one, and a prof, Richard Pimentel, from Cal Poly (San Luis Obispo), picked it up before me, and purchased it. When we returned from the trip, he sent me a bird book.
On that same trip was a guy named Dan Piel. He was a graphic artist that once directed a Madison Avenue marketing firm, and was teaching at Cal Poly in the Graphic Arts department of the university. He sent me an original oil painting that now hangs in our entry hallway. He did a painting of John F Kennedy that now hangs at the Smithsonian.
