Before setting out on this excursion, I made a fairly detailed plan - where I would sleep each night, how many miles I would ride and on which roads, and a list of possible things to do in each city.
Then I proceeded to ignore the plan almost completely. The only things that stayed the same were the people I was visiting and the states through which I drove. The atlas was an infinitely better resource than a stack of printed Google Maps, even when it occasionally directed me to a campsite that seemed not to exist.
It turned out my endurance was better than I had anticipated, so even after leaving three days late, I caught up to the plan by the time I reached Colorado. Here are the final mileage calcuations for each day, and the total trip.

Why an atlas and not a GPS? Firstly, because many, many places along my route lacked cell reception. And secondly, because of this:
It knew where Planet Fitness was. It dropped me in the middle of that mobile home park in the bottom right corner and told me I had arrived at my destination. What?
