If you notice, you will see that this book is a series of conversations between Feynman and a couple of friends, and all are given credit as authors. I read this awhile back, and it is quite amusing.Feynman also had a thing for the Tannu Tuva, the Tuvan SSR in the Soviet Union, and managed to get himself invited there, but died before he made the trip.
At a later date musician Paul Pena made the trip and got a prize for throat singing. I think he went with one of Feynman's pals. The film "Henghis Blues" was made about Pena's trip. It is very good, assuming you like Pena and Tuvan throat singing. It is certainly unique. Kyzyl, the Tuvan capital, is farther from an ocean than any other city on Earth.
