In July /August 2011 we are planning a trip to see a few sites in the west. First or last site would be Glacier National park, next Yellowstone and or Grand Tetons, and then either last or first would be the Grand Canyon.
First how ambitous is this drive for 2 - 2 1/2 week vacation?
Second I would like to fly into or out of Vegas for one leg of the trip where would be the best other airport near Glacier? Spokane , Billing Montana or some other city?
