Non-Toxic, Pallettes or Wood Scraps (Northern Myrtle Creek)

I'm building some raised garden beds, so I need non-toxic, as in untreated, lumber. Most palettes are just pine or cedar, but if you want to get rid of some larger pieces of untreated scrap wood, I'd like that too. Also, if I manage to get enough wood, I'm trying to build a temporary deck for the summer.
