My dad nearly broke a long troutless slump fighting a 16-inch rainbow in fast water. It spit the hook after a while.
A school of large common shiners feeds in a frenzy on
Tricorythodes mayfly spinners which were all over the surface on this July morning.
It seems somebody lost a fly on a tree limb as they floated down the river, and this bat flew by and attacked it and got stuck. Either that, or the bat caught their fly as they were fishing and wrapped it around the limb as he was fighting to get away. Either could happen, although the former possibility is a bit more likely.
