I just ordered a couple of books of maps. One is a 2014 Rand McNally road atlas. And another is the Wyoming book from a series of road and recreation atlases by Benchmark. I really enjoyed poring over the dead-tree New Mexico map I got for free somewhere on the last trip. And it's pretty useful to be able to plan a few days ahead even if you don't have internet where you're camped. Besides, maps are inherently cool.
And I promise to remember that the map is not the territory, as Korzybski reminded us!
