I've never lived in a region where the airports aren't accessible via public transit other than Eugene. Perhaps if there were a hotel or two built then when the next leg of EmX (likely either River Rd or hwy 99) gets built there will at least be some shuttles to public transit.

Naturally, I don't really have a dog in this fight since I don't fly. My business interests are all on the West (Best) Coast and I reach them by train or bicycle when I have to deal in person. I would feel guilty and selfish if I used a plane just to save a bit of time.
