That makes sense. The upper peninsula of Michigan is really more like Southern Ontario.

Contrary to what Dave Hillman says, we are still not the fifty-first state.

Two diagrams on tensile modulus and tensile strength vs. immersion in stem and water vs time up to 1,000 hs. Can send offline if you are interested. Inge I have the same interest - physical properties of laminate with changes in humidity. My interest is in vibration performance of military boards, and we have determined that laminate stiffness definitely plays a role. However, we would also like to know if "wet - Somalia" versus "dry - Saudi Arabia" locations also affects vibration performance. Thanks in advanced.
