Cache is a bison tube that has only a logbook. Please bring your own writing instrument to sign the logbook and replace as found. OshawaOgre has posted several of these types of puzzles on his FB account, and I thought it would be an enjoyable way of getting coords. Thanks OO.
Solve the puzzle below, and enter the 3 digits into the certitude to get actual coordinates for the cache.
Congratulations to timotheon & The Hunting Rabbit on the FTF!
