This site has been confirmed by the City of Walled Lake to be a separate Drive-In from the Walake in Walled Lake. It was opened sometime after WWII and was closed after a few years of operation. It is now an empty lot.

This facility was not so much a drive-in, it was more of a walk-in. One sat outside and viewed the movies. I lived a very short distance, 232 East Street....long since burned down.
