My Grandfather had a 20'x20' shed out back. That's where he had his drill press, lathe, and other woodworking tools. It was the "Skunkshack", and my Grandmother DID NOT go in there.
While I can, if I wish to, smoke anywhere in my house, I often go out to the "Rat Room" in the garage for my cigar smoking. Several years ago we had in infestation of rats and mice and they basically destroyed this off-room to the garage. I have my Grandfather's old lathe, drill press, and the other woodworking tools in there, along with a window unit A/C, space heater, decent sound system, 36" flat screen, a recliner and loveseat, and a couple shelves of books and bottles.
When I feel like a cigar and/or don't want to watch WE network, I head to the Rat Room. The name itself keeps her out!!
