I miss them, too!!!! I haven’t seen a drive-in movie theater here
The only one I know of where I live now is about an hour away form me and the last time we went by it after wine tasting there was a line of cars clear into the street.
So they are still popular.

I think they should come back. I believe they would be a hit these days.
I remember in high school days, people would hide in the trunk to get in free. I never did that.
Thanks for sharing, Kamaldeen❣☘
