What a coincidence. I was just this week trying to remember Dan Osman’s name. I read an article on him back in the 90s (Details magazine if anyone remembers that) shortly after his death.
Rubber Duck, if I remember correctly he pioneered in free climbing and rope jumping, and as the video shows had that 90s ‘wild child’ thing going on. After setting up a jump he was found with a pistol in his truck’s cubby hole by a park ranger (I think), and was sent down for a few months. The first thing he did on release was drive back to the jump, but the ropes had perished while he was away, so snapped with fatal consequences.
I could be wrong but I think that was the general gist of it.
