^^^^Funny you say that...a group of us did what we called Bungee Jeeping one year out at Truckhaven (Tierra del Sol Desert Safari location in SoCal). We were following a water run off up a hill, it ended at a vertical bluff at the top. One of the group dropped a strap over the edge to see if it reached the bottom...it did. Game on...we began lowering each other down the bluff, our rigs hanging from a strap. Stupid...ABSOLUTELY, but we pulled it off.
I know you're wondering how we got the last guy down...the first guy down went back to the top and lowered him down, then backtracked back to the bottom.
