When jiggin raps, continually bounce them off the bottom with a steady rhythm. The whitefish will pin them when they hit bottom and you'll feel them when you pull up on the next stroke.
Take atv. Be courteous and go slow on the bridges the guides put out. Travel with my utv was fine. Saturday fishing was kinda tough. Fished 50-80 ft of water. Today was better. Fished 46' . Got off when the wind started blown good. About 2. Ice was making lots of noise. Didn't wanna be stuck on the wrong side of the crack.
