I have to admit it was just dumb luck. I have caught some nice rainbows out of the same run in the past but never knew this guy was laying in there.
This fish put up a heck of a fight and I was lucky to land him. He kept making a run for the rapids at the tail of the pool and I just bowed up on him and was able to keep him from making it. The line snapped as I slid him into the net. He was almost the 20 incher that got away! Ha
