Another piece that fits your solve. The Indian and horse from the sky. If he would have flown over that I'm almost sure he would have seen that. Indian artifacts were one of his passions. So, in my mind, he would have had to of seen that from the sky! And I'm sure it would have drawn him in to check it out!
Here is why I think there is a treasure! When talking about it, his most prized possession wasn't worth that much. He also claims if someone finds it he would like to buy it back. That might be a set up, or act to make it seem more real too though! It may have cost him a lot to bury and let go of some of his possessions. But the man is attention hungry too! He says this ,when he says "wouldn't it be neat if someone finds my treasure and it ends up in the smithsonian 2000 years from now."(or similar)
When people are attention hungry, sometimes they will pay a lot of money to get it! Even if greedy! Example....sports cars,expensive suits,watches, the trophy wives, the cost is crazy! His cost may have been a 2 million chest of gold. It would be the biggest attention ever! Some of these guys hit a point where money is a tool, it has little to do with the money! They already have anything and everything they wanted. It's the thrill of the chase! In every area of life! This is another one of his sayings!
I was fortunate enough in life at one point, for a short time, to understand this, not to the point of him.(no longer
) Money becomes, just paper. It's hard to understand, We view it different,when we don't have it! A hundred was like a buck to me. Now, I'd be happy to find a ten, and there aren't any hundreds around.
He sees it as a possible damaging thing, and it is! He eludes to this a couple of times. He wants his life story to be looked at and told. Maybe, he feels guilty,proud of his accomplishment with no more than a high school diploma to start with, or who knows. I think A person would do this at any cost! Whether it's 2mil in gold or a big lie! Hard to know! Since he says he has everything he wants, and he is not leaving it to his grandchildren...Maybe, he really did bury it. It was his cost!
So, I do think the treasure could be out there! Maybe not?
There are other reasons too, that I'm not completely convinced there isn't a treasure. Just more thoughts and rambling!
Added instead of another post.....
I know he is being claimed to be a psychopath? Maybe, he is! I wouldn't know! But here are some thoughts just from sitting and thinking about that.
Psychopaths,even have a friend or a person they somewhat trust. (Not in all cases.)Usually someone they do look up to or feel might be an equal in some way, maybe even a challenge to them. They do have feeling for some thing though! Kids,animals,the world,nature,.....something! There is a key! They can also switch! So, death of a parent, life threatening disease, could switch a direction or feeling in an area. They will also go through great lengths to support an idea! Or to show!(in some cases) So, even IF he is a psychopath it doesn't mean the treasure doesn't exist! We just can't believe the reasons why he did it! I've met some and they are very unpredictable if you don't KNOW them. But there is a trigger or key to most that I have met. A doc. or law enforcement has a hard time because they don't know the person they are dealing with. They can only base what they know on past experience or what they are trained to look for. There is not a book or blanket that covers all thought's and actions of every psychopath, just starting point theories or ideas,Commonalities, Baselines(?)! So? Is he a psychopath? How would anyone know? unless they personally knew him and has spent a LOT of time with him!Not just a few interviews or pieces of history, of a what? 80 year life? And he would have had to trust that person to even give a hint! I'm nothing, and don't have a degree in anything. I've just been around a few people that I really believe are psychopaths,close, or fall along the same lines. And was? In a sick way fascinated with their behavior!
Psychopath? No! I wouldn't think, But I'm limited to only my experiences.
Sociopath? Maybe? But I tend to get the definitions mixed and there is a fine line really. I still say either one has feeling towards something other than self.(sometimes) Which fits FF's life better , if you wanted to put a label on him with the claims being made?
If it was only money he was after? He wouldn't have shelves and collections,passions. He would have sold that stuff and took the money! So, he does have feelings and attachments to things other than money! The books are about him, and what he wants to show. Not the money, I think the money might be secondary. OH, probably important! But I don't believe it is his main goal! Control is his goal! Look at me, what I've learned,what I have accomplished, Look at what I see in the beauty and freedom of nature, fits what I see of him so far. He paid for his Grand daughters medical school, under conditions even, That she practices in a small town and does house calls for the first two years. Control? Yes! But why? To show her something HE wants her to see. That's his cost! To show what he wants! It fits, an Idea of why he would put the treasure out there in the first place. But who knows? These are just some thoughts!
