If you like a good riddle, Forrest Fenn’s leads to a few million dollars worth of treasure, hidden in the Rockies.
The poem/riddle can be found at http://fennclues.com/the-poem.html
Besides Reddit, my favorite place to go when I’m mulling over the clues is https://dalneitzel.com/ . His searcher stories make me smile.
The poem looks simple, but this one has been going for about a decade. It’s super easy to spend a lazy afternoon falling down all the rabbit holes.
