My whole house is a man cave since I got divorced some years ago. If its nice, I'll have pipe or cigar on the deck but only pipes in the house. I mostly smoke downstairs in the heart of the man cave, my den/workshop, although very little work gets done there. The dogs sleep, scattered about and I puff contentedly. My new gal says no smoking in the house so I guess that she won't be moving in any time soon.
