I'm an amateur metal detectorist/prospector, and after researching a site and hoping to be on the verge of something I've never ever thought to myself, "better call the FBI and let them know what I'm looking for." Obviously I've never looked for nor found any even remotely close to what these folks found (the best thing I ever dug up was a $5 gold half eagle). Like Neuro said, what is wrong with people? How does this even enter their minds?The Paradas spent five years digging in a cave on state land and two more years drilling atop the cave before going to the FBI in January with their evidence.
