The interesting thing about the story is that the man with the plow says his father was part of the camel brigade that buried the gold. If that is so, why hadn't the father dug it up long before then? Or if it was supposed to remain hidden, why did the father expose his knowledge that it was there, and that apparently there was more of it? For those in the area, it should be simple enough to track down the location and current owners to see if a detector could find anything the plow missed.
