I went on a safari in South Africa. It was truly amazing. I can't wait to go again. Of course, you have to have a fascination for animals. If you do, I highly encourage it.
I had never thought about it, but there's a fence all around Kruger National Park to keep the animals in and people out. There's no "fence" around the Everglades for example so it was a little different when I think about it. Kruger is about the size of Massachusetts.
