I was in heavy cover on small side channel of the S Fork Snoqualmie yesterday. Hiding behind a large root wad, I dropped my #16 dry fly into a likely looking pool. Normally, the line went tight as the current took my fly downstream. But in this pool, the line stayed limp, kind of like the fly was levitating (weird, huh?) Maybe a small bird picked it up? Maybe an ailien was messing with me? I popped up, looked over the root wad - and the culprit was - a spider web had caught my dry fly. This happened several times over the course of the day. I am impressed that the fragile spider webs have the capacity to steal my dry flies.
