I can’t imagine why on earth they would tell anyone about it.
Before and after they moved out of California to a Tax Free, Pro 2nd Admendment, Pro Fracking Republican State...
It's California.
Telling people about it means news reporters show up.
There's a good chance some of those reporters will be accompanied by video cameras.
That means that there's a chance that the finders will be on television.
That, in turn, means that maybe they'll be seen by millions of people. Some of those people may be agents or talent scouts for the entertainment industry.
Therefore, there's a chance that they, or their faces, or bodies, or voices, or personalities, or stories, or something, could lead to a movie deal.
They figure that the chance of meeting with foul play as a result of publicizing their newfound wealth is worth the gamble, because it gets them their first fifteen minutes of fame.
That’s no biggie. I found $20 million worth in rare coins and didn’t tell a soul.
oh wait.
