I'm on the east side, Wenatchee to be specific. For half of the year we have heat on in the house and for half of the year the humidity inside is less than 40 percent. I also carefully watch the RH in my shop and I'm very careful about the room where I store my wood - it is also my wine cellar and stays at 45% and 50 F year around. My message to everyone who has asked or is interested in humidity is to check it if you can (you can buy a cheap little hygrometer and calibrate it easily) and control it one way or another. I'm starting to look forward to more calls from people with sharp frets, wonky action and cracked tops.
