I gave up when it was obvious that the car was going to slide off the cliff if I did anything else, and walked a ways downhill to find help. Eventually I found someone who drove me back into town. I got back home at about 5:00 AM and crashed for a few hours. Then I woke up, drove (different car!) to a friend's house and we both went back up the mountain to retrieve the car. We towed it out after barely saving it from falling off the cliff.
As I drove back to town I thought to myself that a cigar might be a special treat after an ordeal like that... And that was pretty much that.
