I'm getting brave, and having my wife drop me off at Davenport Gap on August 1st on the way back from my sons baseball tournament in Myrtle Beach.....5 days of sunburn and bleachers, then straight to the trail! I'll hike the 40 miles(approx.) back to Clingmans Dome where my wife will pick me back up......I hope(she hasn't agreed to that part yet. She DID jump all over "dropping me off") My biggest concern is water sources. Does anyone know what the water sources are like that time of year, or is it strictly just dependent of rainfall?
