So every day I drive past the field pictured above and the three file cabinets that are inexplicably located in the middle of said field. Except now there are only two. Where did the missing cabinet go?
While I'm sure there is some boring, ordinary reason behind its disappearance, I prefer to imagine more interesting scenarios.
Perhaps the cabinets contain the remains of Jimmy Hoffa. The body parts are distributed among them. The missing cabinet contained the head, along with the only way to identify the remains of Hoffa - his teeth. So, acting on a hot tip from a double agent for the FBI, the field's owners had to quickly dispose of the tell-tale cabinet and dumped it in the nearby lake.
Wait, maybe it contained the complete findings of the Warren Commission, along with a film made from an alternate viewpoint than Zapruder. This film shows clearly that Bobby Kennedy was responsible for his brother's death. Oliver Stone hired ex-Delta Force soldiers to sneak to the field in the cover of night to steal the evidence. It is to be used in his next film, The File in the Field.
Or it most likely it contained unretouched photos and film of the faked Apollo moon landing. The owner of the field is a former cinematographer who was paid off by the government to help fool the country into thinking that man could actually land on the moon. NASA, fearing that the film would leak out, had the cabinet airlifted to Area 51, where aliens will assist in destroying the evidence completely.
Yeah, I know that the cabinet probably just succumbed to rust or had a hornet's nest in it, but I think my explanations are far more entertaining.
