Yesterday, for the first time in my life, I lost a fly box. Not an old crappy fly box with a handful of flies, but the fly box, the only trout box I carry when fishing. A Richard Wheatly stuffed to the gills with wet flies, terrestrials, streamers, spinners, midges, emergers, scuds, shrimp, bead heads, etc.... You name it, I probably had a couple wedged in my box. I'm thinking I lost anywhere from 300 to 500 flies. One stupid slip in the river cost me a lot more money then I care to admit. You can do the math.
