:) well if you guys hadn't stacked the deck of the allegiance vote with a flood of illegal immigrants (just kidding), it still would be ours.

Actually, based political leanings, Washington, Oregon, and California might
be thought of as Baja Canada.

Denny,
As long as the US military does not want to know about "wet" Vancouver and
"dry" Alberta Badlands.  Contrary to what Dave Hillman says, we are still
not the fifty-first state.

Hi  Leo,
I have some data about hydrolysis for a glassfiber reinforced PWB  type that
is similar to FR-4. 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.

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.
