Twin Falls, Idaho (KMVT-TV) Drive–in movies, once considered a thing of the past in many parts of America, are now starting to make a comeback nationwide.

Despite the odds, Interstate Amusement in Twin Falls has managed to keep two drive–ins operational for decades.

But, changes in Hollywood could mean the downfall of one of the Magic Valley's beloved past times.

In 1958, the drive–in theater industry was at its peak with at least four thousand operational nationwide.

In the 80s, daylight savings time, advancements in indoor sound technology and a gas shortage changed all that.

"It pushed more people indoors, but it pushed people away from the drive–ins," said Larry Roper, Managing Director, Interstate Amusement.

Big cities had an even larger problem to deal with.

"The drive–ins were taken over by a lot of gang kids. They became very rough places," said Roper.

Nowadays less than four hundred exist across the nation.

But, recent reports show a resurgence as new outdoor theaters are opening across the u.s. claiming people like the idea of watching movies without restrictions on chatting, noisy children and cell phone use.

"It's kind of like they've all of a sudden found it again. We have people as far as Boise driving down to the drive–in," said Roper.

"We like to sit in the back of the truck and eat popcorn And, I like Brave. It's awesome," said Josh and Harlowe Bartlome.

"That you get to sit outside in you car because it's so comfortable," said Kennedy Bartlome.

"Watching the movie and getting to spend time with my friends," said Madison Rudner.

"Probably seeing the movie on the big screen and seeing how big it can be," said Avery Dewit.

"Probably that they're an authentic American experience that's dying out," said Tanner Fowler.

Whatever the reason, the twin falls' drive–ins are seeing numbers they haven't seen in a decade.

But, unfortunately the future of the two historic landmarks are unsure.

"The major studios have announced by the end of 2013 they want to eliminate the use of 35 mm and go pure digital," said Roper.

If drive–in owners can't afford the fifty thousand dollars to convert to digital they'll be forced to close, which would mean the end of the Motor–Vu...a Twin Falls tradition since 1946.
