Traveling to Tri-Cities, TN (Johnson City, Kingsport, Bristol) in a few days. Must see photo spots?

Also will be spending the first day of my trip on Knoxville. I'm taking a FF camera, 24-70 f2.8, a few small primes, a 6 stop ND filter / CPL, and my drone. What spots should I check out / should I consider any other equipment?

Assuming landscapes, Roan Mountain is great. The AT crosses the highway at Carver's Gap, and a relatively easy hike takes you to the top of Round Bald. The views there are stunning. Here is a map from a blogger that has been very useful for me...https://www.google.com …COQr_aFu3V2IKve​9Gms29q5rc

Each spot links to a detailed blog post. That really is a beautiful area, and shouldn't be too busy now, since there is usually a lull between summer and leaf season.
