I would like to think it happens to the best of us, because it does. Michigan trout streams are some of the most difficult to fish. Catkins, cedars, and tall grass force you to use the Steeple or Roll cast often. Your time on the river is supposed to be fun.
Don't let a mild set back like in the picture get the best of you. Laugh it off. I make light of these melt downs with stupid statements. Like when a client piles up his floating line on his fly I say, "The fish aren't Italian, they don't eat spaghetti". I've done the same. Patience is the lesson of fly fishing, take a deep breath, re-lock & load. A knotted up fly line is one of the smallest problems you will face in life.
I just love it when I'm struggling with a knot and a large trout is slapping the water right next to me. You can either laugh or cry, try laughing you'll live longer. So when that hang up in the cedars happens (and it will happen) and you have to field a dumb question from your buddy like "What are you doing up in the tree", I like to answer, "Oh I have a pine cone fly on and I'm trying to catch a squirrel ".
My Father used to tell me that my smart butt sense of humor will get me into trouble some day...so far he's been wrong...and life and laughter goes on.
