I loved driving around Nevada. My wife and I drove “The Loneliest Road in America” from north of Reno to Ely. Lots of open spaces there!
395, the Extratrrestrial Highway is also pretty open.
I drove The Loneliest Road in October, you really get a sense of the vastness of the West. I even exceeded the speed limit by, ahem, 1 mph.
The night skies in Arizona are spectacular. I had to pull off the road one night outside Needles just to look at the stars. It’s incredible what is unviewable in most of the US at night.
The drive from Las Vegas to Tahoe or Reno has some pretty empty stretches.
I thought it went from Carson City to Ely and beyond to Utah. At least that’s what I drove in 2014 (U.S. 50).
