I love ghost towns. We haven't been out venturing around Nevada yet, but did it often in Arizona. I know we are missing out and need to go.
It's cool.
Even just driving out to Ash Meadows or Death Valley is neat (once the temps drop) there is so much to see. Baker, CA has some neat sites also... Every time I drive out there I see something new...It's so relaxing.
When my dad was alive my folks took the RV to a lot of ghost towns it was like Bonnie Springs in Red Rock Canyon in Las Vegas without the actors!
There is a lot of great info online about ghost towns. This is one of the most popular and I know many that have been there and enjoyed it:
