I'll never forget the last time I went to a drive-in, I was still living in New England. I had a crummy old '76 Chevette, and brought my two daughters and two of their friends. They all decided to watch the movie from the ROOF of the Chevette. I had brought a gallon cooler of lemonade, and as I sat in the driver's seat watching the movie, somebody on the roof knocked over the lemonade and there it was pouring down the windshield. (My helpful daughter said, "Well, Mom - just turn on the wipers" ;-)
