There were black helicopters in the air around the airport and social media was abuzz with seeing all kinds of law enforcement set up from Belgrade to Four Corners. And now we know why: Vice President Mike Pence was in southwest Montana visiting Big Sky.

We don't know the official reason for the VPOTUS visit, but we know he made a stop at the Big Sky Fire Department. Check out the photo above that the Big Sky Fire Department posted on their Facebook page shortly after the Vice President's visit.
