A few years back, we were out riding our horses, and I noticed something shiny about 1000' down the hillside, across the valley in a ravine and I could not imagine how the car got there, and what state the driver was in. We could tell that there was no way it was visible from the road, so we radioed it into the rangers.
Apparently, a guy pulled into one of the road scenic pullouts to take a picture, got out of his car...and you can guess the rest.
He forgot to put the car in park or shut it off, and while he was taking his phot, in slow motion the car rolled off the edge, and drove more or less straight down the ravine.
It took most of the day and three large semi-wreckers, using all of the cables that they had to fish the car back up. I have no idea what that tow bill was, but I'd be very surprised if the car wasn't totaled out.
I was just happy nobody was in it.
A few years later, we had a little old lady drive off the edge of the same road, dropping only 30' or so, but the car wasn't totaled invisible from the road she was on, and it was a week before a rancher checking on his cattle happen to see the car. I heard that she survived, but spent time in the hospital; not bad for an eighty plus year old.
All the best,
Peter
