A very pleasant walk along the Bibbulmun Track. Once you have solved the puzzle drive to the listed coordinates and take a walk along the Bibbulmun track. The walk is very easy and pleasant and not too far. You will also pass by another cache GCHBQ1. So two for the price of one if you haven't already achieved a find for that one.
Beware the red herring - there may be one or two. Don't let them frustrate you and rune the puzzle.
To Isaac Baldwin, who took my idea and converted it into the wonderful graphic you see before you and then put up with my continual requests for additions. - Thank You
