Just a simple hide & thank you for completing my adventure lab! I hope you enjoyed it.
Because I feel obligated to say this, DO NOT GO TO THE POSTED COORDINATES. THERE IS NOTHING THERE.
You will need to use the Adventure Lab app to receive final coordinates for this cache. They are revealed after completing one of the stages, but you'll have to find out which one! You can access the coordinates at any time after completing the stage by viewing the journal for the adventure lab.
