ANYONE can be a passenger in a car going from point A to point B. But being a respected, reliable, interesting, tough, practical, funny, and calm road tripper - that calls for a Montana girl if you want the best. There is no better kind of person to travel with on the road.
Her name is Croft. She wears cargo pants and travels the world in a soup-ed up SUV on overland expeditions. This isn't Lara Croft, but it definitely sounds like some Tomb Raider action. I swear this Montana couple has THE dream job.
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.
