MyFishFinder.com Just like iceshanty but warmer
My question with the floors are will they freeze to the ice on those cold days?
Shapell 6500 is a good shack great price and tough
I've heard enough about Polar Bird to be impressed. The floor idea is a good one as well. That being said, for me and how I fish, I wouldn't consider them until they get some usable windows. If you don't mind having a shack with virtually no windows, I would definitely consider Polar Bird.
I have cabelas 360tc and it is great I really like the Windows all the way around hence the 360 it is also all black so great for sight fishing.
