[Greenbuilding] Alt to pressure treated wood for deck

[JAY WALSH]

I'm chiming in a little late to this conversation and hope I'm not repeating
this suggestion. Have you considered Black Locust for the deck and/or
sleepers?  Black Locust wood is extremely hard, resistant to rot, long
lasting, and used for many outdoor applications. I've worked on several jobs
where it was used for decking and sill plates in stead of PT.
