A friend told me that his grandfather's dying words were that his money was buried 30 steps from the southwest corner, behind the barn.
My mother worked in a nursing facility for many years taking care of the elderly. An old gentleman patient she cared for and described as one of the most intelligent people you could have a conversation with, told her before he passed that he buried his money beside the last fence post, on the county line, behind the barn. She said he had no family left and never had any visitors. She believed that he just did not have anyone else to tell. I will add that it was also because she was kind to him and took time to talk with him.
These men lost their farms and pretty well everything but the clothes on their back during the great depression of the late 1920's early 1930's. They never trusted a bank again not to say what they thought of paper money. From that time until the end their currency was gold and silver, their banks were behind the barn. These men were not the only one's to use barns as cache spots. Barns were and are landmarks. Outlaws used barns the same as the owner did when it came to establishing their own banking system, but probably using a little more distance. The outlaws were employing the barn owner to watch their loot without him knowing. Behind the barn does not have to mean front and back, it means away from traffic, out of sight. When hunting these old barn sites keep in mind that the cache will not be where livestock, horses, or people trod. Near old gates, fences, or the edge of the break of a hill are good spots to look. You never know what might be behind, beside or near the barn.
May all your trails be smooth and your treasure sites many.
Best Wishes and Good Hunting
