It's a biz. Some peeps will pay big bucks (pun intended) to go and shoot an animal in a fence. Doesn't make sense to me but I guess it doesn't have too.
There's an elk farm near my house. Not for hunting but for the antlers. He sells them off in Japan for major money, sells the meat locally as well. It's fun to drive by and check those big bastards out!
My Uncle told me a story about being at a game farm in Wyoming where a guy paid 4k to walk up to a bison and shoot from 10 feet away. That bison was like a pet that was hand fed by humans it's whole life.
Eccentric rich folks sure do seem confused on the aspects that make accomplishments special.
