Hello! I am planning a week long trip to Boise in June. I would like to fit in a 2 day trip to Yellowstone National Park. I have figured out that it would be approx a 9 hour road trip to the park. In order to save time (and unfortunately probably miss a lot of scenic sites along the way) I have been wondering if they are flights available to the area and has anyone ever used them or have suggestions where I can get information? I haven't been able to find anything online. Thanks!
