Years before the Sac and Fox lands were opened for settlement, lived a miserly, old man who managed to save up a few thousand dollars. He suddenly took ill and wasn't found until he was on his death bed. He was so weak he could barely speak, but managed to point towards a dry creek bottom and whisper that it was buried under a rock by a stump. For many years afterward people searched for the money but never found it. The search area is south of Kendrick, Oklahoma on what in 1920 was the Sporleder Farm. A records search in that county should turn up who is the current land owner and with a bit of luck you might just be the one who turns over the right rock.
Good Luck and Good Hunting
