Hello Josh, many comments come to mind here. I even found a hilarious picture that screams red neck. I have seen what you are talking about, on exotic ranches. But I have no idea where they come up with the seats they mount on top of their Jeeps for hunting purposes. Maybe they just take the legs off of those fiber glass seats they used in cafeterias or something.
I have got to share this picture with you though. It is priceless.
Here is a hunting bucket seat.
