Yes. There's one. It's called the Century Las Vegas 6 Drive-in and it's located at 4150 W. Carey Ave. in North Las Vegas, directly across from the Fiesta Rancho (off Rancho Boulevard), 702/646-3565.
Affectionately known as "the Vegas," this drive-in opened in 1966 with one screen. It was expanded in 1971, 1974, and 1992, which gave the drive-in six screens. The original screen blew down in a storm in 1998, so today the Las Vegas 6 has only five screens.
The Vegas is open year-round and presents double-features on each screen nightly (the first feature plays again after the second feature). Audio for the movies is provided over your car's radio by local-vicinity FM broadcast.
Admission is $6 adult; children under the age of 12 years are admitted free. On Tuesdays admission is $4 per person. The ticket booth is open from 7 pm till midnight on Friday and Saturday, 7:15-11 pm Sunday and Tuesday, and 7:15-10:30 pm on Monday, Wednesday, and Thursday.
One other drive-in movie is left in Nevada: the El Rancho Drive-in located in Sparks, Reno's sister city.
