glass and wood, etc.
Fiberglass is pretty elastic stuff. It's not at all clear to me that
woven glass over ply (I'm not talking about taped joints) does much more
than protect the surface until after the plywood breaks. OTOH, uni
glass, which we don't tend to use, might be much more structural, since
its fibers are straight. Composites with straight fibers are much
stiffer than with fibers that weave around. I've got some numbers
someplace for this. Uni glass is usually a pain to deal with, tho.
What's wrong with skiing? At least X-C?

Cross Country is fun but not enough speed,which is what got me hooked
in the first.My kind of boating is certainly not fast but then again
I can't swim either,which kinda gives me some excitement....perhaps I
could try cross country sking out on a partially frozen St.Lawrence
River never knowing when the ice is too thin.....so there is my
secret adrenalin rush :-0
> Fiberglass is pretty elastic stuff.Hmmmmm......I think it might depend on exactly what type of resin the
fiberglass is sitting in and just how many uni-directional layers are
involved,but I am open to being convinced otherwise.

trips off the edge of the trail and into one too many spruce trees.
