Re: boots for Africa?
A lot depends on where in Africa you are hunting. Seeing gemsbok on your list I would assume you are going to southern Africa but terrain can be very different from one area to the next. Example the Eastern Cape has lots of very rocky mountains, & you will need boots with stiff soles to prevent hurting your feet. Other parts of the country are flat & sandy.
I use a light weight, ankle high, hiking boot with a aggressive sole. I also use gaiters (not snow gaiters) to keep the grass seeds out of my socks & other trash out of my boots. I generally wear long pants, light weight, green cotton that is double faced.
I also take two pairs of boots & alternate them every day so they have a chance to dry out from perspiration. Take a extra pair of socks and change at noon if necessary.
Weather, as mentioned it is generally the dry season, however one day in August ten years ago we had rain, sleet, & snow all in one day in the Eastern Cape. I always take a light weight waterproof jacket just in case.
Remember to bring some camp shoes. Also once the sun goes down the temperature can change quickly.
Watch the sun, I wear long sleeve shirts, not for warmth but to keep from getting burned. Look at the light weight fast dry shirts often used in fishing.
I have a small bag I put into the truck with some "stuff", extra socks, jacket, sun screen, extra ammo.
Another thing, stop at Walmart & get a big bag of Jolly Ranchers, the trackers & staff love them.
Last thing, keep a eye on US Customs. They are in process of changing what we need to do to travel out of the country with a rifle.
