I recently started ice fishing crappie, and love it. During the day I usually find them in the deep pockets around 20 FOW, as soon as the sun sets they vanish. I have drilled many holes trying to locate them and I am positive they leave the deep water. During the night I have tried mouths that enter a bay, shallow water around the deep holes and even flats. Where do they go!? What should I be looking for to find the crappie when the sun goes down?
