Meant to be a sister cache of our nearby Coordinate Complexification.
The cache, of course, is not at the posted coordinates, so please don't search in the middle of Route 15. It is hidden just a short ways off the beaten path by the ruins of an old artifact of a bygone era. Muggles will be nearby but shouldn't hinder your search. I often wonder when I stumble upon these things how they got here, and what their history is. Maybe you know if you're familar with Lafayette. I haven't yet run across the story. I did notice a few small poison ivy plants near the final, but you do not need to mess around in it to find the cache, so please don't go there.
Have fun! Oh, bring a writing implement.
