John R. Brinkley dreamed of being a doctor. Unfortunately he couldn't achieve that goal. He could however say he was one, and became known for implanting goat gonads into patients. Brinkley was on the forefront of quack medicine, disinformation, and conspiracy theory radio. 

Forrest Fenn, a wealthy art collector, decided to create a treasure hunt to get people outdoors. He filled a chest with treasure, and hid it somewhere in the Rocky Mountains. The lure of the treasure led people from around the world to analyze the clues, and search for the treasure. The hunt led to injuries, death, and betrayal.
