You may wonder what the actual treasure is at the end of all these hunts. When catering for a large amount of people, you can’t have one pot of gold at the end of the rainbow otherwise you render the rainbow redundant when the first person has found it. To extend the metaphor, you make the rainbow itself the treasure, with a token pat on the back at the end. The reward comes from solving all the brain teasing clues which will take you on an engaging adventure. If treasure is required, it can be a draw at the end of the day. One day, we’ll find a friendly farmer and plant something special in a field that needs ploughing, but until then, enjoy the ride.
