About 5 years ago, I was out at a spot on Spring Creek throwing a size 4 Weamer Streamer without really knowing much about fishing streamers (other than dead-drifting, swinging them down-and-across, and stripping a bit). The water was up and off-color, the weather was rainy, and on the first cast in a new spot I missed one of the biggest browns I’ve seen on Spring. The fly hit the water and a split second later this large fish porpoised (I could see the entire back of the fish) going after the fly.
Naturally, I did what any fisherman with buck fever would do: promptly pulled the fly right out of the mouth of this brown then stared at the water where it came from, slack-jawed.
