My wife hits a milestone birthday in 2013.
We are planning on visiting New Zealand in December 2012 / January 2013 but I've just had a thought that she loves the Grand Canyon (she has visited a few times and we both went in 2009) and the Yellowstone National Park (I've never visited).
How feasible is it to visit both National Parks on one vacation?
Driving between the 2 is around 1300 miles I believe which would waste about a week of average travelling or possibly 3 / 4 days of pushing hard?
Flying is also an option but you have to hop over to Denver and onto Jackson Hole from there.
Is it worth driving all that way (I suspect not).
(I've not mentioned this to her yet though!)
