We saw elephants on our trip; all solo male bulls. And none of them were happy to see us - if we got closer than 20 or 30 yards, they would charge us or show us their ass while walking away into the brush.
It was the one time I felt most like an invader riding in a truck looking at wildlife. Our guide Francis did a decent job respecting the creatures and their space and wanting to share the surroundings with us. But it's a tough situation - riding around in cars to look at animals is noisy and invasive. The elephants were the only creatures we saw large enough to challenge us on it.
