If you don't know about the Nutty Putty cave, it's a cave system that has now been permanently closed after the horrible death of a caver who got stuck there. Look up details at your own peril. The name "Nutty Putty" is unrelated to the death and references the putty-like soft clay found in many of the passages, so you may cleanse yourself of any horrid mental images brought upon by speculation on the name.

If he never had claustrophobia before, I wonder if he developed it during his last 24 hours alive, stuck in that cave. Poor guy now eternally entombed in cement. People might say "Rest In Peace" out of habit but I'd find it hard to rest in peace if I were him. My soul would be restlessly haunting that place forever in agony.
