I have heard bits and pieces of that story, nice to hear the whole thing....and from the horses mouth!
If I may add another tragic shelter story....
I was on my thru hike back in April 2000 and had come off the trail in Hiawassee, Ga due to bronchitis. I went to the Doc there in town who gave me a shot and some meds and was told to go to bed for a few days. So, I did all that and went back to the trail that Saturday. I was still feeling bad but good enough to hike. I plodded along and made it to Plumorchard Gap shelter where I set up on the upper level pretty early in the day. I took my meds and promptly went to sleep. Later in the day the other hikers made it to the shelter and there was one hiker who had to know everyone's trail name. He didn't see me until last. I told him my trail name and when he found out who I was he said he had been following my journal and wanted to shake my hand. With that, he jumped up on a stool high log that was on the lower platform. As soon as he was up on the log, it tipped over sending him flying out of the shelter, banging his leg on the picnic table. It looked really bad and by the next morning was even worse. He had a nasty knot on his calf the size of a tennis ball. Needless to say his hike was over.
Moral of the story---don't shake hands with people on the trail! :-)
