I haven't done Shuckstack, yet. I may do it this fall, I was going to do it last fall and loop it while crossing over Gregory bald then descend back to Fontana Dam (the name of trail escapes my memory at moment), but the park shut down during government shutdown. lol. I love Rocky Top. I explored the northern half of the Smoky, so any of my future trips are kind of geared towards southern sections.
