My wife and I are planning a road trip within the US from the east coast to the west coast for 2-3 weeks at the end of May. After some early investigation, we love the sound of a route between New York City and San Francisco with our must see destinations being the bookends New York and San Francisco and the preliminary other 'must see' places for us are Yellowstone National Park, Las Vegas and the Grand Canyon before flying out of Los Angeles back to Oz. In summary, we like both the big cities and love the great outdoors (especially around the Rockies) and everything in between.
We would appreciate any advice on which route people would recommend, any highlights on this route, any advice on our trip length, the time of year etc etc. We would consider to take some flights in order to fit everything into our itinerary ie - San Fran to Vegas to LA or others?
Thanks in advance,
