There is a very good contingent from Namibia too, and some very good outfits at that. Your estimate is probably about right.
This is boutique hunting; there are all kinds of reasons hunters don’t want or have no interest in Africa. They cant bring back meat is especially a huge issue, its a real hang up , doing guided hunts in general (not feeling they accomplished by themselves), worried about safety, food, fear of flying, long flights……the list goes on. And then there’s perceived cost.
Everyone I know is more then content sitting in a tree stand overlooking a food plot day after day waiting for a whitetail deer. One local guy I know has an arsenal of top grade safari capable rifles; big bore bolt actions, double rifles; and multiples of each. Reads every safari book, magazine, videos and he just won’t go, and I’m no longer asking.
