In 2010 september, I am planning a roadtrip that will take me through the Western US in about 3 weeks. Most of the route is planned and validated, but there is one part that I am unsure about.
I will be going from Yellowstone to Grand Canyon, spending 2 nights and 3 days on the trip.
What can you recommend as a good route between the two? I know it's a very open question, but any input will be greatly appreciated.
