Jon,
I took a big male baboon and scared another nearly to death on my hunt in Namibia. I, too, think that they are pretty cool looking critters. Like Don said, a disturbed group of baboons can ruin a water hole for the morning, but that's what is great about Africa...always another place to sit. In my experience they are the most wary and smartest critter you can chase. That makes taking one, especially a big male, a real challenge and worth the effort.
