Buckeye Corners is like many sites in the western US - it used to be on the map, and now...not so much. It doesn't stop people from remembering what was. This hide is in a remote (way off the beaten path) road in the Loess Hills region of central Nebraska. A place where cows outnumber people by A LOT.
You are looking for a bison tube hidden in/on one of the three signs that designates Buckeye Corners as a thing. Bring your own writing utensil. Hide should be easy to find, but be aware that the ditches are steep so watch your footing.
