Makeshift Swing

I've known people who would have done exactly this. I got out of rock-climbing when I realized my double-jointedness was a recipe for disaster:

An experienced rock climber died early Tuesday after he climbed to the tip of a 10-story crane on the University of Colorado campus and then used rock climbing gear to create what amounted to a giant swing.

Ryan Young, 22, may have been blown off course by a gust of wind, sending him crashing into a building across the street, CU police Lt. Tim McGraw said.

"As we all know, the winds were blowing last night, and as we also know, crane arms aren't tied down," McGraw said. "They're somewhat akin to a large weather vane. A little movement on the end of the crane could have a huge impact."
