Thanks, Adam & Hans. Good info.
Having worked in Kingsport many years, I got spoiled by living within reasonable driving and hiking access to some beautiful wild and stocked trout streams in the Greene, Unicoi & Carter county areas of the CNF. I didn't discover fly fishing until my children were adults. My grandchildren are getting old enough to perhaps take to the sport, but they live to the west of the Smokies. Tellico and Citico are not really the answer. The Blackberry Farm type fishing is a bit too pricey for me. I guess that leaves the Crosseyed Cricket and other trout farms, but I don't think they much cater to fly fishermen.
My son and his boys and I are going to the WNC Flyfishing Expo tomorrow. From that I hope they really get the itch to try the sport. Given all the other things out there trying to woo our young people, that would be a good problem to have.
