Marty’s photo of the day #3592: When Deb and I went to Zimbabwe to complete the last chapter in my first book, Cool Creatures, Hot Planet: Exploring the Seven Continents, I was determined to see the country on foot, not from the back of a Range Rover. The reason was for moments like this, when I’d hear a rustle and realize I was coming up on an elephant. This old bull was huge—something one can’t fully appreciate until standing there and knowing the nearest vehicle was many miles away.
