As I was taking photos of the first elephant, I heard a loud cracking sound, as of a large branch being snapped in two. The thing was that the sound seemed to come from behind me out the left side of the car. It seemed almost in slow motion that I turned and looked out the passenger window, where I saw only four huge legs, the bottom part of a trunk and two very large tusks. Imagine my embarrassment in being snuck up on by an elephant! This one was a bit agitated and he bluff-charged by vehicle just after this was taken.
