I did the touristy thing and went to the top of Clingman's Dome (6643 ft) It was windy and it was chilly but the panaramic view was fabulous. I walked, maybe, 100 yards down the Appalachian Trail and then I did a very lazy thing. I popped out my foldable chair, had a picnic lunch and watched the mountains for the rest of the afternoon.
Because I had not used very much energy in the afternoon, I decided I needed to do something for exercise so I drove to Laurel Falls which offered a 2.5 mile round trip hike. Again, 1 mile up is still some work in the mountains. But there were loads of people at the top and the peaceful waterfalls wasn't very peaceful. Going down was a breeze.
