I find it hard to believe people are gullible enough to brag about finding money/gold/whatever. But they walk among us. If I won the lottery, the last thing I would do is tell anybody about it. Finding gold in a tank? fuggeghettboutit.
I read about a guy, who had an older home. He discovered a hidden passage that ended up enlarging his home by a few hundred square feet.
I read it in a newspaper and my only thought was he was a fool for letting anybody know, because his taxes will probably increase.
