Peter Bro is right on the spot. Kerstin it's dark inside them little shacks, and as you can see in one pic, it's got 4 round holes that are covered in that particular one. But in a regular (normal) shack they drill one hole. And supposedly in the daytime the sunlight comes reflecting thru the holes in the ice, if they keep the inside of the shack dark ie: door close. It's suppose to be a scene man ? {LOL} They can actually see some fish swimming by the close surface. I myself have never been inside one, but this is what I was told... Fact or Fiction ?
