The thing to remember here is that Doc willingly filed to go non-reporting years ago while he was working on this. As others have pointed out, when you put HRI (200+million) and his other private companies into the conglomerate we are worth high silver on that alone. Then add in all of the stuff we speculate about (and Doc hints at) and you start thinking $5 might be cheap.
