Yeah I smoked up that way once when I was housesitting for my girlfriend. Not that she would have cared, but her mom would have. Just filled the room with steam, shoved a towel under the door (a wet towel works best), turned the fan on and toked away.

It sucks having to sneak around though. Big Calhoun, I can't imagine what it would be like having to hide something like that from my wife (assuming I had one). Of course I'm not criticizing you or anything, but that must really suck. I'm glad my girlfriend is alright with it.
