Just recently, the Bozeman Yellowstone International Airport has complete two very important projects. The projects together cost around 23 million dollars to complete.
If you're in the mood to miss your flight out of Bozeman or sit around the gate area for an extra 45 minutes before your flight - ask a local what time you should show up at the airport. There's a very decent chance they'll give you crappy, non-detailed, and not particularly accurate advice.
Did you happen to watch the skies on Monday? It was a constant stream of private jets taking off from Bozeman's airport, heading home to wherever these folks actually live.
