A random thought that hit me as I was in the amsterdam airport with the bazillions of other people traveling to Mt. Kilimanjaro (the flight was as large if not larger than the LAX to Amsterdam flight).
You can tell safari travelers by the way they dress, but it’s pretty funny to see the variation. Khaki is definitely the color of choice (with reason, bright colors either scare animals or attract tse tse flys, so I’m told), and there were lots of people in their safari vests. But the true fashion item of choice were the convertible pants (pants that zip off segments into either shorts, or capris, sometimes both on the same pants).
