"Fly Fishing and Fly Tying" have kept my interest, I suppose it's the combination of the two subjects that keep my interest.
One time I heard of a guy who was an article writer of sorts who submitted his stuff to magazines like Field and Stream and such, but who never fished or hunted himself - he simply researched whatever the subject was to be and then let his vivid imagination go to work. Little wonder many of us develop an underlying cynicism! (LOL)
