The Memphis pyramid was a sports arena and concert venue in the past, eventually the city built another venue that wasn't shaped stupid so it sat abandoned for a decade or so before bass pro bought it.
I know you are just being silly, but to answer your question, the point of those groups (ducks unlimited, pheasants forever, whitetail whenever, turkeys tomorrow, raccoons all noons, etc) is to put money into conservation of those animals so that their populations stay great enough that they can be hunted.
So yes, the goal is for the ducks to be unlimited.
It was not a Bass Pro Shop then. It was The Pyramid, concert venue / arena.
I saw Jimmy Page and Robert Plant play there in the late 90's. It was totally awesome, they played almost 3 hours of Led Zeppelin and Page/Plant songs. John Bonham's son Jason was on drums.
