I have Ian's book "Great Smoky Mountains National Pak Angler's Companion," but just be clear, the publication I am referring to above
is a folding 18" x 24" map on one side and a guide on the other (species description, hatches, popular fly patterns, etc.). The map identifies nearly 40 streams and includes icons for the game fish species they hold. It is printed on water resistant paper so one can both sleep and
swim with it.
