Have my reservations in hand for a section hike thru the northern end of the Smokies in a week and a half. Starting at Newfound Gap and finishing by going down the Chestnut Branch Trail to my car at Big Creek. First night at Icewater Spring shelter (late start that afternoon), second night at Tri-Corner Knob shelter, third night at Cosby Knob shelter, then back to my car the fourth day. Last Labor Day weekend, I did Clingman's Dome south to the Dam with a stay at Derrick Knob and Mollies Ridge shelters. That 13+ mile stretch from Derrick Knob southward was a butt-kicker for me. Is the northern part any easier? I'm especially concerned with the section between Icewater and Tr-Corner shelters. It looks like the only water source in that stection is at Pecks Corner shelter, and that is about 1/2 mile down off the AT. Any recent information on trail and shelter conditions and water along this whole section? How are the bugs? Any other info on points of interest would be appreciated. Thanks.
