never in our house...I'll smoke on the back patio ost of the year or in the garage with a heater blowing on my ass in the winter...fun, no but it wil suffice
...we're getting ready to put our house up for sale and get out of this godforsaken state, so when we move (hopefully it won't take a year) , I'm going to either go for a basement setup or if no basement, then I'll hook up a ventilation system in the smallest bedroom to turn into a "smoking lounge"
