For too long I have tried to convince my church customers that the temperature isn't the issue, it's the lack of humidity control during the heating season. After 25 years, I might have convinced one or two... for now... until someone else suggests it's a temperature problem, or they become convinced it's evil spirits, Rush Limbah, or somethingorother. BTW, I highly recommend that you, and everyone else who reads this, find and obtain a copy of the book I mentioned. It has all the information you would ever want about wood, and more. Even if an authoritative source doesn't count in a group discussion, I find it comforting. Call it a personality flaw. Ron N
