has ranked the top 10 death defying cities in the U.S., and Twin Falls is on top of the list.  Over the years many daredevils have tried different stunts at the Snake River Canyon.  Back in 2005, a BASE jumper attempted to set a new world record of 50 jumps in one day.  One of the most famous stunts was back in 1974 when Evel Knievel tried to jump across the Snake River Canyon in his "skycycle."  The 486-foot tall Perrine Bridge is the only bridge in America where you can legally BASE jump anytime with no permit.  Bend, Oregon, was ranked second. Ogden, Utah, and Rock Springs, Wyoming, also made the top 10.
