Concept Art Locations from Fallout New Vegas
I also found a few places that were not in the game but featured in concept art if you look closely.
The first, Starlite Motel, is in North Las Vegas, directly north of the Old Mormon Fort. The second is Roy’s Motel and Cafe (which is not a motel or a cafe by the way), which is located south in Amboy, California. There is also a smaller one in Barstow, California. The last is the former Hialeah Motel, which closed in 2015. It is/was located on East Fremont Street.
