We still have one in my area.
We had a drive in theater only a couple blocks from my childhood house. We used to bring our own popcorn and snacks. Since my parents insisted on smoking, despite my severe allergy to the smoke, I’d have to sit on the roof of the car. But it was still so cool to watch the movie from your own car. No strangers laying a couple feet away from you like at the modern indoor theaters (which I don’t attend). Everyone was quiet and well behaved. Another part of former America gone. You could not have the same orderly atmosphere with today’s undisciplined kids.
