The BEST part of a Drive In...
The Back Seat!
I love the old drive in movies. Circa 1965 with a date in my 1958 GMC pickup. Dammit, pickups did not have a back seat back then. On occasion we actually watched the movie. If I was lucky my grandfather would let me use his 1960 Buick Le Sabre. It had a back seat the size of Dallas.
I miss those days. The popcorn was good also. I do not think we every finished a bag of it.
