I hope I didn't create the impression that Nevada has "speed traps." It doesn't. The speed limits in the rural towns are not unreasonably low and the enforcement is not because the local jurisdictions are trying to use speeding tickets as a revenue source. The strict enforcement is for safety. For example, U.S. 50 between Fallon and Carson City is one of the most dangerous stretches of highway in the state. Car v. wild horse collisions are common. We had a double fatality near our home in Dayton due to excessive speed just about a month ago. It is common for people to out drive the illumination of their headlights at night so when a horse suddenly is in front of them, it's through the windshield before they even can get their foot on the brake, much less slow down.
Nevada is filled with wonderful things to see and a drive through this stark and magnificent countryside is worth the time. But as John suggests, it's a good idea to not pass gas stations when your out in the middle of nowhere.
