Going On Safari? Come Up And See Me Sometime...
Wise tourists who have done this before and have the chiropractor's bills to show for it may elect to take a smaller rig this time. Consider if your ambitions and plans might well be suited with a camera that has a 30X zoom lens, 4 second to 1/2000 second shutter, manual aperture and shutter wheel, and GPS built-in. And a Leica lens. And a proper viewfinder on the LHS of the body. And full HD video with stereo sound.
And fits in your top pocket as you go through the door of the airplane. And for which you have not paid excess baggage.
You may not know which wine to drink with your biltong or cheese fries, and you may not know a bear from a banjo, but you can capture the fun and the scenery without making a guy or a mule of yourself. You will be less likely to attract the attention of the local pickpockets, or at least they will concentrate on your passport and wallet, if you are not carrying a camera shop on your neck. The grizzlies and hyenas will be less likely to demand a fee for posing if you do not shoot with a DSLR.
You'll still have to deal with the Europeans, but at least you will have your hands free while you do it.
