Who Doesn't Love a puzzle? Me. . . sometimes. Especially after I've stared at clues that make no sense to me for far too long. I'm terrible at this kind of cache, but I had this Idea while trying to solve Cow Juice by Seven of Clubs. I thought I'd put it out there and see what happens. Maybe it will be a challenge; maybe it won't
Cache is a nano so you'll need your own tweezers and pen. It should be an easy find once you solve the puzzle.
