Kevin, beware the addiction of fly tying. It will get so bad that EVERY time you go fishing, you will have to stop at LRO and somehow come away with new tying materials!!!
Seriously though, I think you will find it very rewarding. Once you tie up several Zebra Midges, you need to come down and try the Hiwassee sometime if they will ever turn off the water... Late winter/early spring on the Hi with those midge patterns can be unreal.
