Double Springs Gap Shelter Mile 196

Awoke at Derrick Knob to freezing rain, sleet and overnight snow. All through the night ice would fall from the trees on to to tin roof of the shelter. Like pennies being dropped onto tin roof. Donned semi-dry rain gear and headed out. Misty rain and freezing fog accumulated on trees and fell off when wind blew. Blow down ice was half inch thick on trail. Weather finally broke about two o'clock as I pulled into shelter. Sun was out and took opportunity to try to dry gear. About 3 miles from Clingman's Dome, highest point on the AT. Talk at the shelter was to get up early and night hike to Clingman's Dome for the sunrise. Why not?
