There really isn't much to see in Nevada, just miles and miles of open country, mountains without trees, and sand . . lots of sand.
The most interesting place in the whole trip across Nevada was our stop in the little town of Rachel, named for the first child born in the community. This town once provided housing for the Tempiute Tungsten Mine. When the mine closed in 1988, many of the residents left. Today the town is best know for it's location on the Extraterrestrial Highway and its proximity to the Nevada Test Site and Groom Lake aka "Area 51".
Not too far beyond Rachel, if you know what to look for, is the infamous "Black Mailbox". It's white now, but it was interesting to stop and see. Mom, being a big Sci-Fi fan, got a big kick out of it!
