I'm sure there's a thread on this somewhere, so forgive me if it's been discussed. My wife has family that lives in Washington State. If we were to drive there, we'd be going through Wyoming and Montana, both of which allow private citizens to own suppressors, according to Silencer Shop's website. I would be taking two rifles with me and two suppressors. I'm assuming carrying a copy of my trust and my stamps should be more than adequate, correct?
