I'll have to check out the Rhebok.
My 2nd trip I archery hunted quite a bit and had some Baboon's within spitting distance, little bit spooky. 3rd trip my friend really really wanted one, but never had a chance while I seemed to be seeing them left and right.
No different that deer hunting in the states, when you're after something it's elusive and when you don't have a tag or have a gun in your hand they sit and stare at you.
