The Mount Clemens Drive-In opened in April of 1952 with a capacity of 1000 vehicles and had been expanded in 1977 to accomodate around 1200 vehicles. The Mount Clemens was built for the Mutual Theatre chain that included many theatres across the area.

Like many of the Drive In Theatres that were built, they were trying to attract and keep a family-atmosphere for their customers. At the Mount Clemens, this included a playground for the kids to play on to keep them occupied while they and their parents were waiting for the main show to start. The playground at the Mount Clemens also included toys that looked like ponys and boats that would appear to "float" in mid-air.

The Mount Clemens audience-area was just a gravel parking area, unlike some drive-ins that had been paved with blacktop to keep the dust down.

In the summer months, the theatre area would be "fogged" to control the mosquitos and bugs but unfortunately upset a few skunks along the way too. This caused more than just a couple folks to end up leaving the show early and have to deal with an everlasting odor from the upset critters.
One of the advantages to the theatre being outside was for those folks that smoked being able to enjoy their habit without disrupting or bothering others.
Admission ticket from the Drive-In
A notable piece of history is when President Nixon visited the area in 1972 to dedicate Eisenhower High School in the Utica Community Schools. He was welcomed to the area by a sign that was laid-out in 70-foot tall letters reading "Mr. President---Welcome" using 700 pound of line on the 20-acre site of the Drive In.
Because of this, Joseph Ellul Jr. (the owner of the Mount Clemens Drive in) received a letter of commendation bearing the Presidential Seal and signed by President Richard Nixon mailed from the White House in Washington, DC. which read:
"The President of the United States
presents this
Certificate of Appreciation
to
Joseph Ellul Jr.
for outstanding performance on the
occasion of the President's visit to
Michigan."

Audience area and Concession Stand (1996)
When FM-transmitters were installed to upgrade the sound-quality of the show, you could tune-in your car-stereo to the audio-track of the film instead of the single-pole speaker that didn't sound very good. Also many folks would "forget" about the speaker-box on many occasions and led to either the speakers being pulled-off the poles, or even the window that the speaker was attached to on the vehicle getting damaged or broken.
Many nights when the film ended and went to white screen, some of the folks would rush in front of the picture making hand shadow puppets just for fun.
Backside of the Main Screen
One night there was even a small meteorite that damaged the main-screen and repair-work could be seen on the screen from then on where it'd been patched.
When it closed in 1996, the Mount Clemens Drive-In was one of the last single-screen Drive-In theatres in SouthEast Michigan, leaving only the Ford-Wyoming in Dearborn the "sole survivor" in Metro Detroit. The Mount Clemens Drive In would be demolished in 1998 or 1999 to make room for the expansion of the M-59 Highway, as well as the relocation of a local Auto Dealership that now occupies a good portion of what was once the Drive-In Theatre property.
