Muley, Those 1/3 are probably the ones with more money than they no what to do with and expect that a guided hunt will be 100% success. They watch the TV shows and say hey that would be fun to try and go do it I would guess.
I would love to go into the back country on horseback for a week or more. I do not have horses so that would be a guided hunt that I could see myself doing. Much cheaper than owning horses all year I would guess.
