I'll tell you what I remember as a kid about drive-in movies. We had a station wagon with a blanket rolled out and the seats down. We might sometimes hide to "get in free". Often back then there was a double feature, with kid-friendly movie followed by a not so kid-friendly movie (I remember something like Escape from Witch Mountain or Ice Pirates followed by some stupid Cheech & Chong movie. To this day I hate anything Cheech & Chong. But the whole thing was a great ADVENTURE!
