Tom,
I'm sure no expert. I read the same books.
The big problem when I was there in 1999 was too many elephants. They want to cull even more but were a catching a load of dung from the animal rights crowd.
They said they knew we were hunters even though we weren't there to shoot. The one thing I heard from rangers, guides and the lodge owner (we stayed west of the park) was what cheap skates and pain in the butts the eco-tourist were.
I would love to go back and hunt but now that I have the money, I don't have the time.
2show, the hunting culture predates the gun culture by a day or so.
