Here is mine.
I wouldn't exactly call it hunting, but it's effective. It is sealed to the elements, I have a small heater and I can get away with quite a bit. I can eat, stretch out if I want to, talk to my buddies on walki talkis if I want to. I even have a small radio with headphones for when I get really bored and the deer are not moving.
I can stay in this blind all day no matter what the weather is and stay dry and fairly warm. I have killed deer on days where if I had to sit in a tree stand I would have stayed home.
I don't drive my car to the blind during the season either, I was doing some work on it in the off season. We have three of these blinds on different sides of a 50 acre property.
