I don’t know if all us fly-fishermen are afflicted with this thing, but I suspect most of us are. Just take a look at our fly vests. A myriad of pockets, zips, buckles and zingers. And if we fish with a backpack, you can be sure it will have hidden pouches, rain cover, waterproof key pocket, secreted expansion zip and the like. Fly boxes: row upon row of little compartments that clip open. And then there is the fly tying desk!
