Sure enough, at the correct places they'd researched, he got a big signal with the detector ! Digging down, they hit solid rebar-reinforced concrete. Ie.: a Steel drum , the size of a pillbox or giant closet, encased in concrete !
But later, after zero results (much like yourself), I began to question the very stories themselves . Began to re-quiz my guides as to their sources, their reasons for believing them to be true, etc... And began to see that I too had merely been wrapped up in treasure fever . And had not done my critical questioning homework BEFORE the hunt. So that I could have saved 3 weeks of my life, driving thousands of miles. Hence now my fascination with the psychology of how the human mind acts when it comes to treasure But while you might not have proof of the existence, yet it is clear from your writings that you very much believe there is Yamashita treasure(s) to be found. Right ?
I gave, as an example, my friend who ... while searching for the yamashita treasure, found a septic tank instead. That was just an example of something that could be found (that, in their mind's eyes, seemed at first like a giant treasure chamber). And, of course, turned out to be something else.
