Drive-in movie goers of the past would pull up beside a metal post sprouting from the ground. At the top of this post would be two speakers on cords. You would grab the speaker closest to your car window and pull it into your car (or as far as it could reach) in order to listen to the movie’s sound.

Laugh all you want, but this was pretty advanced technology for the time! I still love going to the drive-in and seeing photos like these brings me right on back to the good old days.
