To add another angle to Derek's question, the new lite-weight sheetrock that they use these days, is there any actual gypsum in it anymore? does anyone know, or has researched it? not being a smartass, was just curious about that. I'm not sure there is any, or very much, used in the manufacturing of sheetrock anymore..

All the really good ideas I've ever had came to me while I was milking a cow.
