No big predators will be a plus for sure!We are near Portland, Or. Usually not extreme weather, but wet.
Predators are hawks, raccoons, possums, and outdoor domestic cats. Maybe a neighborhood dog, but in 15 Years, there has only really been one pomeranian that we see running loose.
I don't really think I could add any more advice if you're set on using pallets in their intact state. I have never been to OR, regrettably. If you have much in the way of driving rain and/or snow you may consider a more solid wall.
