I've hiked the section between Black Balsam Knob and Shinning Rock before. If the rest of the tral is like that section, then water will be rare. Make sure to bring plenty of water volume.
"The Road goes ever on and on,
Down from the door where it began.
Now far ahead the Road has gone,
And I must follow, if I can.
Pursuing it with eager feet
Until it joins some larger way
Where many paths and errands meet.
And whither then? I cannot say."
