Smokehouses

So how does everybody prefer to build their smokehouses? If you had a smoke house in the mountains, what kind design would you want?

I think we had a topic like this a while back and had some great ideas on it.....even had some pictures of some nice smokers, But mine is made outta wood and it holds the heat at a perfect 140 degrees perfect for amoking sausage. ill try to get some picts of it on here. you gotta make sure its not treated wood but i gota tell you its nice to know my kids dont burn their hands on a metal smoker. just gotta make sure the smoker dont burn down though..!lol
