This geocache is part of the Tri State Treasures XVII "Busy Day Tour", or BDT. These geocaches are meant for some as an introduction to non-traditional types of hides, while providing all with a chance to find a lot of different icons in a single day here.
A Wherigo geocache is a special type initiated several years ago by Groundspeak that makes use of a special cartridge player available in many GPS units and phone apps, to play a cartridge downloaded from the Wherigo website. Reverse Wherigos can be played by entering three six-digit numbers into the Reverse Wherigo cartridge by Waldmeister. Then you can play a cartridge that, instead of telling you what direction to go, it will only tell you how far you are from the final spot. By moving around and tapping on the cartridge again and again, you can deduce how to move towards the final.
There is also another common method used by many geocachers to more quickly solve reverse wherigos, but we'll leave that for someone else to tell you.
To find this geocache using the Waldmeister cartridge available at the link above, enter the following code numbers into the Reverse Wherigo cartridge when prompted to begin your search:
