Hey 78mudbug...They just probably moved out into a little deeper water. They probably did not go far. Just to the closest deeper water on some kind of ledges(structure) or deeper cover (stumps or brush). That is my two cents. I am just envious of you getting to go even if you did not catch much. Hope you had a good time.
But one thing I do: Forgetting what is behind and straining toward what is ahead, I press on toward the goal to win the prize for which God has called me heavenward in Christ Jesus.
