Yeah, I contacted other vets when I had a problem. Len Goss was one, (indistinct) was another one. Charlie Schroeder at San Diego Zoo. Chuck (indistinct) at St. Louis Zoo was another one. So yeah, I had vets that were experienced and I trusted, I always called if I had a problem. During your zoo career, whether it be as a veterinarian or as a zoo director, or education person, what would you consider to be the major effects that affected animal care.
