When I was in grammar school, back in the '50's, my family went to the one just South of Jonesboro, LA. I think the first car we went in was a 4-door Stude, with the rear suicide doors. Only show I remember seeing there was Gone With The Wind.
It must have closed before I was old enuff to date, in the mid '60's. By then, the only one I remember was in Ruston, LA, about 25 miles away. Not aware of any in this area for a LONG time.
The only time I remember going in my '69 GTO, was in either '71 or '72, during NG summer camp. It was at Camp Beauregard, in Pineville, LA, which is very near Alexandria, LA. So, the drive-in was probably in Alex.
According to this, there are none in LA, now.

Wow ! In looking at those in surrounding states, I found this one in TX, which didn't open 'til '04. They now have 7 screens, can have up to 800 cars, and are open every day of the year.

This one, built in '13, has only 4 screens, but has a 1300 car capacity. I had no idea that ANY were built this century, much less any that big. Would be interesting to know what is the most cars they've had at one time.
