The animals are wild, plus the interaction of wildlife and people along the road are pretty wild in another sense. Especially Asian tourists, as every time they take a picture of some special attraction like a historic building, monument, or scenery, they have to be in the picture. Forerunner of the selfie, I guess.
The best one was the Ranger telling about a woman smearing peanut butter on her kids necks so she could get pictures of a bear licking them.
