Many years ago, I went to Bogor, Indonesia, for a conference. It was a great conference, and I loved the quiet jungle setting where we were hosted.
On afternoon, the organizers planned a tour to the Animal Safari in the surrounding areas. At the "safari," it was set up so that you could walk in quite close to the animals and even have your picture made sitting next to a big cat of some sort, or whatever other animal of your choice. It was a sad sight, though. The animals were heavily sedated so that visitors could venture close enough to them. They sat blinking their bleary eyes at us, and I couldn't help but feel sorry for them. I also wondered if it wasn't perhaps a bit more dangerous than advertised. Sedated or not, a provoked animal won't be tranquil forever, and there was very little in the way of controlling how guests treated the animals.
But, the pictures others had made seemed to turn out nice.
