The motorcycle is an illustration of the author’s own ride.
While the line drawing was all done in pen on paper, this was my first foray into watercolor in Photoshop (as opposed to my usual method of actual watercolor on paper).
The interior maps illstrate the routes of the three trips taken over the course of the book. The author wanted the maps to have visual cues tying locations to events in the book, and she often named places on the map after events or references to the text rather than the actual places. For instance in Oregon there’s pie instead of Burns Junction.
