You must first complete the Adventure Lab which will provide you with the cordinates for the final location.
The Adventure will take you on a brief walking tour of confectioner's row, the historical center of candy making in Cambridge. Through much of the 20th century many companies produced chocolates and candies in this part of Cambridge.
Please use stealth when finding and replacing the cache container. Final location is N 42 21.ABC W 071 06.DEF.
