This guy was a professor of something from New Zealand and was combining the Kimberley tour with his hobby of geocaching. He was a real character - very extroverted, usually very funny, sometimes a pain in the A but always full of life.
Don't bother to comment - just telling a story.
Hee hee--can you believe I know a young man born and reared here (actually in a rural, rodeo area) who is a university professor in Auckland? And that his expertise is ancient world history and literature, and he's invited all over the world to give seminars--England, Rome, France, etc., and Harvard Press is publishing his book. Perhaps this man is his colleague.
