Welcome to GeoPi!
Of course, the cache is NOT at the posted coordinates. Solve the problem presented below to find the correct coordinates. Cache is an ammo can.
One of my earliest geocaching adventures was tackling an eight stage epic cache known as GEOBOx, created by andGuest. Eventually I adopted the cache, but decided to re-invent the stages and surrounding area as a Geo-Art that combines some of my favorite activities: mathematics, geocaching, and hiking to see the beauty all around us. I hope that you will come to appreciate mathematics and its humor, and the scenic locations of State Game Lands 83 that stretch to Otter Creek. Be sure to bring good hiking boots, water, snacks, and a QR reader pre-loaded on your phone.
