The Drive-In And The Screen That Needed A Field

A drive-in theater required several acres of flat ground within driving distance of a town. That single requirement explains both why they spread and why almost all of them closed.

The economics were about land, not film

An outdoor theater needed a large lot, a screen, a projection building and a gravel surface. Construction costs were low compared with a building that had walls and seats.

Cheap land on the edge of a growing town made the arithmetic work. The site did not need to be central because the audience arrived by car and parking was the venue.

The same location later became the problem. As towns expanded outward, that acreage was worth more as housing or retail than as a place to park cars twice a night.

The car changed what an audience was

Inside a theater, an audience is a single group required to behave the same way. At a drive-in, each car was a private room with its own rules about noise and movement.

That suited families with small children, who could sleep in the back without anyone being disturbed. It also suited teenagers, for the reasons the venue was famous for.

The result was an audience that overlapped in space but not in experience. People watched the same film in hundreds of separate small environments.

Daylight set the schedule

An outdoor screen is unusable until dark, so the start time moved with the season. Summer shows began late, and the operating window closed entirely in winter in much of the country.

That seasonality made the business fragile. A venue that can only run part of the year has to cover annual fixed costs from a compressed earnings period.

Weather compounded it. A rained-out evening was not rescheduled, and a cold snap could remove a weekend from the calendar without warning.

Sound moved from posts to radios

Early sites used a speaker on a post that hooked over the window glass, which is why drivers occasionally tore one off pulling away.

Later sites broadcast the audio on a low-power radio frequency, and the car stereo did the work. Sound quality improved substantially and the posts came out.

That change also let the theater disappear as equipment. All that remained on the ground was the screen, a booth, and a field of cars with their radios on.

The surviving ones survive for local reasons

Drive-ins that remain open tend to be in places where land stayed inexpensive or where a family held the property outright and had no reason to sell.

Some added swap meets, concerts and other daytime uses, which spreads the fixed costs across more of the calendar than films alone can support.

Conversion to digital projection was a hurdle that closed several. The equipment cost was fixed and large, and a seasonal single-screen operation is the hardest place to absorb it.
