I remember that video posted here of the wasted dude B.A.S.E. jumping off this bridge - right in front of a CHP officer. Upon seeing it, it sure doesn't look all that high for parachuting ( you certainly wouldn't want to fall off it, though )
How long of a rope did you need to rap off the Bixby Creek Bridge? I'm curious because of that guy who B.A.S.E. jumped off of it.
My first "free" ( read "overhanging" ) rappel was also off a bridge - an abandoned bridge in the San Bernardino mountains ( used to be a bridge on Hwy 330, but later bypassed ). Ropes were only 150' then, and a rap off that bridge was exactly that. We just rapped right off the end of the rope. Good thing we didn't know enough to tie a knot in the end of it, that would have really complicated things.
We were still in our "let's test the system, to see if it works" phase.
Let us know!
