Tom: I apologize for the acronyms. Any treated lumber you get from the Borg now will be treated with the ACQ (
Ammonia Quaternary Compound) type treatment. It is considered safer than the old copper arsenic which actually really protected the wood for many years. Everything now is going biodegradable, which means mother nature will have her way much quicker.
Its really all a conspiracy between our elected representatives and the building contractors to ensure they both have plenty of our income in future years. It all started when they outlawed chlordane for termite treatment. Of course, that was a conspiracy, too, 'cause old motor oil works just as well if you don't have water flowing under the foundation. Not to worry, tho. The Aztecs determined all human life on earth would be wiped out in 2012 by a big meteor, so that is when they ended their calendar, so you really only need to worry about that porch rail lasting about 6 more years.

Go
(wonder what response this post will bring
