Great shot bring back memories of my Motorcycle Journies to Nev and Cal. Some very lonely roads. Radar detector and great vision field relate to very high speeds at times. Not gonna say how high my GPS recorded at times.
I got my 1977 Toyota Corolla 5-Speed with 1.2L engine up to 105 MPH on that road back in June, 1978. I remember it well. Nobody else in sight.
Gila monsters love to sit on the side of the road and scoot across it when they hear the vibration of your oncoming car... It's as if they're playing a game to see if they can make it to the other side before you squish them!
