...ummmm... well, let's see now, Joe, we can drive that highfalootin new Montana style S.U.V. up alongst the canyon wall, an' then you can roll out in yer parryshoot and aim for the dust trail down on the riverbank, whilst you lookout for a clear, soft patch in the sagebrush and prickly pear, roll down the hill, and right through the sliding side door into the comfort of the back seat. ( yep, "Life's more excitin' in Montana.")

Airport? Well, would you prefer Delta or Northwest Airlines? Closest airport to Columbus, as LEJ said, is in Billings. Rent a car and drive from there to Columbus. Here is the state of Montana website on travel. Montana Travel Guide
