Ian's & Charity's seminar was what I would call "general" about E. TN waters. That's not meant as a diss on them, but more in generalities than specifics. What was fun was watching & listening the two of them bantering back & forth. Sounded like they have a great rivalry (good natured of course) on who catches the best fish of the day.
Earlier, I was talking with Ian and told him that his E. TN. Blueribbon trout book was a real asset to me when I started fishing the tailwaters. What was really helpful was his detailed maps of the waters, with access points, boat ramps, and best spots to fish. And his recommendations on techniques and flies was a help also.
