Thanks for that. I was unaware of the details of the Wyoming FFA; and for some reason mistook your initial remark as a reference to Montana, even though you said Wyoming. My bubu.
As far as FFA's in general go, I can't understand a state passing one without this provision, unless that was the only way to get anything passed. "If you violate federal gun laws, you're in no hot water with the state (course you never were in the first place), but if the feds arrest and prosecute you in spite of this law, you're on your own" sounds like empty posturing.
