WOW! Some great stories and some tough experiences. Kaboku's is a zinger!
 
I’ve slept on the ground over 300 nights of my life, 11 of those unplanned. Several of those were with no tent/sleeping bag, and yet I can’t think of any that were truly miserable, even one in a damp/wet sleeping bag in a violent sleet storm. Synthetic bag felt like a sauna but was warm.

A fearful night was spent in a goat bed with pebbles falling from the cliff above. I tried to do too much before dark and found myself on the dead end of the goat trail in pitch dark. The only safe course was to stop in the only level spot, not quite as big as my bod. I had pad, sleeping bag and a tarp to roll around my pack and myself. If it had started raining, bringing down more and larger rocks, I planned to crawl down and around the fearsome steep talus below me, to get away from the impact zone at the base of the cliff, and hope there was no cliff dropping off below.
