Here in CAlifronia, HAYWARD LUMBER, a huge and very old lumber company is
selling 'ACQ' pressure treated lumber, without arsenic, with copper.
Apparently arsenic PT will soon be outlawed.

Anyone up on this?  They say "you can eat off that thar piece 'wood."   Umm,
well...

But friend working with it on fences says there are none of the effects that
the PT would do, like irritate his mucous membranes etc.

Of course, keep on with the locust and lesser input ways!!!
