Muggles. From the Harry Potter series, a term that describes non-magical people who are unaware of the existence of the wizarding world. In the Geocaching world, muggles refer to the ordinary members of the public who do not yet know or understand the magic of Geocaching. As muggles don't (yet) understand the rules of geocaching, they often take or disgard a geocache they accidently find...thus removing the cache from the field of play. Thank you, JK Rowling, for the perfect metaphore for this real world phenamenon.
Geocachers vs Muggles. Geocachers and muggles have been at odds since the beginning. Geocache hiders (aka, Cache Owners) have often gone to great lengths to combat the muggle with countless variations on hide styles: hidden in plain sight, insanely difficult and/or small cache containers, bushwhacking deterents, and remote locations. You name it....cache owners have tried it.
Sometimes a cache seeker must use their creativity when searching for a cache as to not look suspicious of those darned nearby muggles. And, sometimes, a cache owner may place a cache in a high muggle area just for the challenge of it. Such is the case here. You got this!!! (and hopefully the muggles won't). Good luck.
