Things you should be aware of with the new ACQ lumber.
1. There are different grades of it. You should be looking for wood labeled
for ground contact.

None of it is suitable for ground contact. Use plastic or concrete footings.

2. The copper will corrode galvanized or zinc plated screws and nails. If
you expect it to last you will need stainless steel hardware or at least
double dipped galvanized.

Exactly. I've been told to expect old style hardware to corrode to nothing
in under 6 months.
