It took a year for the first of Byron's keys to be found. But in 1983, three kids from Chicago - Eric Gasiorowski, Rob Wrobel, and David James - dug a big hole in Grant Park and unearthed a plexiglas cube, inside which was an ornate casque with a ceramic key, inside.
I met with Eric and Rob, in Chicago, in 2014. Along for the adventure was my friend, Charles Moore (who was with me back in 2005, when we knocked on J.D. Salinger's door). After we poked around Grant Park, Eric and Rob took us to Milwaukee in search of another key.
This is a clip from an early cut of our documentary, The Secret of Byron Preiss.
