The cache is NOT at the posted coordinates. This is a BONUS cache for completing the Adventure Lab "Cambridge Bridge Trolls".
To find the actual coordinates for this cache, you will need to complete the 5 stages of the Adventure Lab. Then, correctly answer the unlocked question at each stage and you will be given a letter in each journal entry.
The 5 letters form a word. Enter that word into the checker to get the final coordinates.
REMEMBER
Be sure to leave the same number of items that you take from the cache.
Leave a TB to take a TB. Please log them and move them along quickly
