Geocaching puzzles have taught me a lot of brand new things about ciphers and codes over the years. Sometimes I get lucky, and can round up the solutions rather quickly. But just when I might think that I am clever, I run into one that really freezes my enthusiasm. So rather than roaming in frustration, I put those nuisance puzzles in holding and turn to one of my other hobbies to capture my attention. I hope you learn something new and interesting about one of my other passions from this puzzle cache.
