In 1933, the first “park in” theater opened in Camden, NJ. Its owner, Richard Hollingshead, obtained a patent on the concept. In 1949, his patent was overturned, and that year, drive-in theaters started popping up all over the US. Coincidentally, that was the year that the Tri-State opened two miles north of downtown Miami on Route 66.
They were looking to open in March or April, but that was a bit optimistic.
The above ad gives folks some details about how the drive-in theater works, since many if not most hadn’t seen one yet.
Sometime after the great flood of 1951, possibly in 1953, another drive-in theater opened a mile south of town, on 66. It was called the Sooner.
The Sooner’s location made them vulnerable to flooding. The article above announced a temporary closing due to flood damage. However, no further advertisements appeared in the News-Record for the Sooner south of town. On January 2, 1955, it was mentioned in an ad as one of the five Miami theaters. But this was the last mention of the original Sooner.
At some point between 1961 and 1965, the Tri-State was renamed to the Sooner. According to historian Fredas Cook, it was to take advantage of the much nicer Sooner sign formerly used south of town. Fredas also points out that the original Sooner was a traffic hazard due to its screen facing the highway, that may have contributed to its being closed shortly after opening.
Now, of course, the Tri-State/Sooner is long gone, a Wal Mart sits in its place. But Miami residents can visit the Admiral Twin in Tulsa or the 112 in Fayetteville for a genuine drive-in theater experience within a reasonable drive.
