Sadly the two drive-ins in my area re now a Lowe’s hardware store and a massive empty lot.
Mom and dad put us in PJs, and spread blankets in the back of the station wagon because we would never make it through the movie, and honestly for me it was more fun eating popcorn and people watching, or watching Star Wars with no sound playing on another screen across the lot!
The one I recall had a playground to keep the kiddies occupied if they weren’t interested in the movie.
