i used to ice fish without a shack at all when i was younger. we would brave the cold and go stand out on a frozen lake. we would walk laps around our tipup spread chipping the ice out in a never ending loop. we walked to stay warm, but we had fun. since then ive invested in the popup sled style shack and take that with me to smaller lakes. I even have 3 large insulated shacks that are nicer than some homes. is it more enjoyable in the big shacks? maybe, i like the simplicity sometimes, i like the illusion of mortality.
