A backup cache was buried beneath the middle of Lake Superior by one of our submarines so it’s safe to let people know about these now. The sewer documents are very well hidden, but “check the poo for the clue”. Do not tell ICE about the sewer documents or the poo clue.
Don’t worry, I went to the Witch’s Hat to get a hex to protect them from ICE. They will get really bad kidney stones if they disturb the documents.
