So help me with being the best kind of client of which we can assume you are exemplary. Based on your understanding of hunting ethics and desire to submit yourself to the "vagaries of the natural world," would you spend 20K on an elk hunt in an area with few elk or hire a guide with a reputation of rarely taking elk? Assuming we are not hunting behind fences, would you rather hunt a sable or nyala where they are abundant, or on the fringes of their habitat where an outfitter is lucky to take one a year? And what exactly is that contract that you sign if it isn't a transactional agreement?
What
@375Fox and I are saying, however mistaken he is in his priorities,

is if a particular game animal is the primary purpose of a hunt, whether a royal elk, mountain goat, buffalo, or leopard, the best sort of client will do his due diligence to pick an outfitter with the area and skill set to conjure up that opportunity before then resigning oneself to the vagaries of the hunt. That isn't seeking a guarantee - it is employing common sense.
