We were in Florida's Lion Country Safari many years ago. It's a park where you drive through and all the animals are free to roam as that wish. We came upon a herd of elephants on a small hill beside the road. We stopped the car and a friend rolled his window down about 3 inches. A baby elephant came to the car and was running his trunk along the open window. My friend was playing with it with his finger, saying, "Here, elephant elephant." The papa came down the hill and put his tusks against the front wheel of the car and gave a gentle, but firm push. The car rocked and scared the hell out of us all. Papa took the baby and went back up the hill. I have no doubt that the huge papa could have easily flipped us over. Luckily, he just gave us a warning, "Don't fuck with my kid."
