Clue 2: The Park
In the Summer 2010 a group of six artists embarked on a journey to Chernobyl to develop a secretive Plan C.
Once in the Zone, they threw metal nuts. Maybe in search of an answer, they ventured into the abandoned amusement park of the ghost town of Pripyat.
Finally the group located what they were hoping to find, the Red Ride. They picked through the irradiated remains. One of them got contaminated.
While they were there a load of scavenged materials left the Zone.
Where the materials went afterwards is still unknown.
