Fantasy Map: National Parks Transit Authority Map
Produced for the Sierra Club and very nicely done indeed. Having Yosemite and Yellowstone as the main “hubs” seems very appropriate. Sadly, I’ve only been to three of these parks - Grand Teton, Yellowstone and Crater Lake - something I’ll have to remedy.
Finally, I love the disclaimer: *So incredibly not to scale and also fictional.
