I was getting out my daily vitamins, and one the silica gel packet came out. I grabbed it, and tossed it aside for my fly boxes. Then I got to thinking how many other guys know about the great use of these things, so here I am telling you. Everyone has fallen victim to the "rotten fly". You know, the ones you forgot to dry out, before putting them back into the fly box. Then the next trip out, you have a possible rotten fly, where the material is still wet and the hackle/marabou is falling apart, or a rusty hook. You can find them in just about everything these days. Vitamin bottles, OTC drugs, shoe boxes, new electronic equipment boxes, etc. Save those little silica gel packs, and put them in with your flies. It's worked really well for me. Of course, I'm sure many here are already aware of this little "trick", but just thought I'd share just in case someone doesn't know.
