Old school vintage Vegas at it's finest. Fremont Street (the original Las Vegas Strip) and its surrounds are a favorite. Old casinos, cool murals, and elope on a secret rooftop with more Neon than a dance music festival.
In the middle of the desert, the Nelson Ghost Town is a brings history to life. An impressive collection of antique cars, busses and even a plane crash, not to mention the "Little House on the Prairie" style wooden chapel. An hour's drive.
