Want to visit the National Parks in the USA in one epic road trip?

Somebody has gone to the trouble worked out a route for you to visit all of them. This year was the 100th anniversary of the National Park Service. And to celebrate it one bloke has gone and optimised a route that will take you through 48 states in mainland USA.

Summary:
Mainland USA, not Alaska or Hawaii. 47 National parks, 14500 mls and 2 months to do.

I plan a trip doing all of the US mainland States excluding Alaska next year before I come home and have seen a similar map but with all the states in so I may look at combining the 2 maps. I think i would plan more than 2 months for that trip though or you would literally be driving past the parks rather than enjoying them.
