It was an interesting day. A black Rhinoceros was spotted way off in a field in Serengeti National Park in Tanzania. I started taking pictures and it turned and headed to a spot right behind us on the run. These guys can move very fast. It was aiming for a safari car that had ventured off road (a park big No-No). It crashed into the car at full speed then backed off and butted it again three times. The car started to drive off at full speed and the rhino kept after it. We headed out of there at full speed as well. Quite unforgettable.
