I am going ice fishing often in my afternoons for the rest of this winter. Yet, when I leave the hole for a night or a couple of nights, it freezes over, and I really don't want to re-drill all the holes with the auger. No snow will get in the hole since, it will be surrounded by my ice hut. Is there anyway that I can keep it from freezing? I was thinking if I put a long log in the hole, then when I went fishing again, I could just bang the log a bit, then pull it out.
