I'll have to revisit this next winter. Wife and I are just starting to build a new house; by next winter I'll have my own den for smoking, movies, reading, etc. It'll have a nice deep window so I can look out onto the woods, and another smaller window for cross-ventilation. Right now we're living in a mobile home on the premises. I can't smoke inside since my wife has asthma, so I have to smoke in our 12 x 14' storage shed. Since it has no heat, I usually smoke in the afternoon, when the sun is on it. At least it has windows so I have light and can adjust for some ventilation. Come warmer weather I'll smoke outside, unless it's windy. Needless to say, I can't wait till next winter! If this post is still open then I'll post pics after I get it furnished.
