The one that's nearest where I live now has been closed for about 35 years.
The concrete base for the screen is still there and the 'hills' for the rows of cars are still present. I only went to one movie there, back in 1980, to see The Jerk with Steve Martin.
Spent most of my drive-in time in Michigan. There was one in the next town over from where I grew up and it had an unofficial nickname of 'The Passion Pit".
There were better ones farther away that I would go to a couple of times a summer. I never minded the inferior quality of the speakers.
The first time I ever saw Thunderbolt and Lightfoot was at the drive-in, in my sister's '68 Tempest.
They would sometimes show oddball stuff at that drive-in. Once I went there and one of the early shows was a collection of Hollywood bloopers hosted by William Conrad.
