What are you going to use on the Gemsbock and Kudu? They are tough bastards. Show us your mounts when you get them back.
Make sure the clothes you take are well-constructed. Africa is hard on pants and shirts. Also, bring along a nice pair of sunglasses. Africa is no place to sport the $5 gas-station specials.
Have fun and don't be afraid of the local food. In general it is very tastey.
