GLENDALE, AZ - The Valley's only drive-in theater says business is up 43 percent over the last four years.
Manager Kas Moser says part of the reason is that families find drive-ins a good value.
Nostalgia is also driving the increase in business.
Jaime Harris told ABC15 she's been going to the Glendale 9 since she was a young child.
She remembers the days of clipping the speaker onto the car window.
Today the speakers are gone and so are the 35 mm film reels.
Last April the Glendale 9 Drive-in replaced all the film projectors with digital technology.
Moser says Glendale 9 is the largest all-digital drive-in in the nation.
