And did Antifa show up and riot? What about Montana and Wyoming?
Both Open Carry since they were founded.
Both have "tourist" areas out in mountains/college areas that are chock full of nuts (including one antifart twitter in Missoula), but even there it's still Armed Society = Polite Society.
(I still chuckle about the school East of us has a sign on the door says "Members of staff are armed for safety"...and the ones don't bother about the silly sign.)
