We probably have the same kind of climate as where you are, Azrael, but I totally understand Benoit's problems. Even in Toronto, which is southern Ontario, probably a good 5-6 hours south of Benoit, the humidity changes are crazy from summer to winter. In the summer, it's nothing but humidity. In the winter, everything gets soooo dry from the lack of humidity + heating. I'm always worried about my axes getting warped from the season changes, and I can feel the action change from summer to winter on my acoustic.
