Dudes, I've played with knots on bungees too much. I whole-heartedly suggest buying a prepackaged joiner. I've not tried Mark's but if he says it works, I believe him. If you try it and don't like it, I'll buy it from you minus postage. In the past I've used aluminum tubing from Torque and Recoil

I have not flown there, but I seem to remember cliffs with road access at Dillon Beach, west from Petaluma. I recall a large sort of subdivision thing on the hill that seemed to be owned by people who only used the homes for vacations. As usual for the central/northern coast of Cali, the
