My wife and I honeymooned in Botswana many years ago. On our first day in the bush we watched a pride of lions on a kill. Our driver radioed into camp, "fill up the water pans, the lions will be thirsty tonight." Sure enough, late that night the lions came in and drank at the water pan about five feet from the front of our tent. Mind-blowing experience to be lying in bed watching them right there.

We've since explored quite a bit of Southern Africa. The Namib desert is incomparably cool.
