I'd do it...
How long has that cable been there? How securly is it anchored? When was the last time someone competant inspected it?
When I was about 20 I went deer hunting in a national forest. I found a very old deer stand. Old 2x4s, big nails, perched precariously about 20 feet up a tree. Been there God knows how long. Like an idiot, I climbed it. I sat there for about 5 minutes, and shifted around to look behind me. I heard a creak and a snap. Let me tell you, you would be amazed at how fast a white boy can descend 20 feet.
I do not not trust super annuated redneck ingenuity.
