and is visible from the bridge as well as various vantage points along the Canyon Trail. A memorial to Knievel is located near the bridge; it was dedicated in September 1985, at a small ceremony attended by Knievel. BASE jumping The Perrine Bridge is a popular BASE jumping site known all over the world; it may be the only man-made structure in the United States where BASE jumping is allowed year-round without a permit. Jumpers often use the nearby visitor center as a home base before and after parachuting from the bridge. The first documented and video-recorded/photographed jumps from the bridge were in 1987, by three residents of Twin Falls (former U.S. Army paratroopers) who static line jumped the bridge using military surplus MC1-1B parachutes. It was done after a test drop of a 55-gallon (210 liter) drum in a T-10 parachute harness and canopy was used. Multiple successful jumps were conducted without incident or injury. In the early 1990s, bungee jumping and parachuting off the bridge gained popularity, but was still against the law; by the end of the decade, BASE jumping was legal. In July 2006, Dan Schilling jumped off the bridge 201 times in 21 hours to raise money for charity; Schilling was hoisted to the top of the bridge by a crane after every jump. Three base jumpers have to date perished jumping from the Perrine Bridge; Brandon John Chance, James E Hickey, and Kristin Renee Czyz.
