Thanks everyone....The heavier piece even looks different....wow - 4 1/2
pounds more water than the other one !!!! Just one 8' piece was different
than the rest....Almost looks like Douglas fir - The green preservative is
very dark on this one but it could be because the wood is so wet.


Would be very rare for PT to be Doug fir--it's far too dear to be used
up that way by the mills...

I would suspect that if you dry the two pieces for a month or so they'll
be very similar in weight. It is quite possible they're different
varieties of SYP and one is more open grained than another so there is
some inate density difference, but I'd wager pretty heavily it's
mostly simply water...
