All trout anglers have tied themselves up inside these Gordian knots of fishing strategy. It’s one of the things that makes trout fishing so much fun. But in untying these knots, water pulsing around my legs, fish just waiting to be caught, I’ve found a surprising benefit—one of the other reasons that make trout fishing such a surprising pleasure. I bet any trout angler—or every angler, for that matter—has experienced this. It’s often said that we fish to escape the real world, with its tangled webs of responsibility and challenge. But more often than forgetting about reality, this is what happens to me: I step into a stream with a head full of stress—what to do about two family cars with the CHECK ENGINE lights blinking, how to win the next round of Deadline Whack-A-Mole—and hours later, on the trail back to the truck, solutions begin to bubble up in my mind. By focusing so tightly, time and again, on the riddle of where a fish holds in a single seam of current, my brain seems to break free of all the torque that’s locked up the gears.
