So my early New Year's Resolution is to be more proactive in sampling the waters I fish for bugs. I really want to hone in one the colors and characteristics specific to some tailwaters and tie up some flies to make some solid imitations of my own, versus the generic midge/mayfly nymph/caddis nymph/stonefly imitations and whatnot. I was wondering where you can get those small vials to stick in my pack while I'm fishing for bug storage? What liquid do you store your bugs in - rubbing alcohol, vodka, anything else? Any help is appreciated.
