It was a 2600 mile trip solo in 6 days, so I didn't take a lot of time off, but I did want to sketch every day to give myself a mental break and enjoy the places I was driving through. I sketched one morning at a scenic pullover in South Dakota and did the same the next day in Wyoming. These are my two favorite sketches of the trip, and it's no real surprise to me that they are the fresh, morning ones before I got tired.
