You know, I don't make enough to have a "movie room" downstairs... I have a tv... and those of you who have been to my house would proly agree, that It could be humid down there while sitting on a salt bucket , or swinging in the hammock.
Just kidding Ron, I see plans come accross my counter all the time at the brickyard with movie rooms or media rooms... you just let it slip that your house is a ton bigger than mine...
RCS - Fred. They make a neato switch called a humidistat... you can use it to controll the humidity in your home - and when to turn on a fan... I keep threatening my wife that if she won't turn on the fan when she showers, I'm gonna install one. a 12 minute shower adds alot of moisture to the house. Then she leaves it on other times, and blows perfectly great airconditioned air outside all day... I would flip for the switch, you wont be disappointed.
