The folks at Frabill posted this video of a thick school of perch that scatters at the sound of footsteps on the ice. I know the book is closed on this winter’s ice fishing (though it didn’t feel like it this morning) but it’s worth watching anyhow so next winter, you understand the need to walk softly and carry a small (jig) stick.
This is why we don't stomp our boots on the ice, @rick McEachern
