Whitley Gap Shelter
The AT in north GA and NC took a beating with some bad tornadoes a few years ago. One night some hiking companions and I on a week long section hike ended up at Whitley Gap shelter just as the weather moved in. We were totally spent after a long day and just gulped down some food and headed for our shelters.
I set up my hammock/tarp while one pair crawled into a mountaineering tent. The others all headed for the shelter. As the night went on lightning cracked and the wind howled. Guy lines that had been banjo string tight when I went to bed slackened in the high winds and my tarp began to flap against me like a sail broken loose. I was hanging from a pair of foot diameter maples in some low underbrush, hoping to break the wind. Well, it wasn't working...and the trees swayed so much I was afraid they were going to snap my tarp ridgeline (zing-it doesn't stretch much).
Every so often the wind and water would build where it sounded like a freight train coming down the valley. I knew for sure this was the front end of a tornado roaring over the hillside. Every time I though "well, this is it".....figuring I was about to be incinerated by a bolt of lightning or crushed under one of the trees in the area. This went on basically all night. Fortunately I actually stayed warm and dry, just scared of imminent death.
Come morning my friends crawled out of their tent like there had been a gentle spring shower. Never was I more jealous of the ground dwellers. On the other hand....my friends in the shelter were far more miserable throughout the night than me. The front of the shelter was facing right into the oncoming wind so everyone was soaked. So this was the scariest night out for me and also the worst weather....
