A couple of weeks ago, four of us went to do a 170' pit. While we were all at the bottom, a group of non-cavers came to look at the hole.
They could easily see the Chevy pickup that was 100' away. We had gear lying around everywhere. Our rigging and rope obviously went down the pit.
And STILL.....one of them threw a rock in!!!
Luckily it missed me (I was ascending and assumed I had knocked the rock loose with the rope) and the others were out of the rock fall zone.
These were people that should have known better. Personally, I think a 3rd grader would have known better.
Anyway, should I fill out a more detailed account for American Caving Accidents?
