Do drive-ins still exist? Our local one lasted until around the early 90's. It was a fun place to enjoy. As a family, we saw such films as Hey, There, It's Yogi Bear and Mary Poppins, as teens usually horror movies (including Race With the Devil with Lara Parker) and we'd pull the old prank of sending one unsuspecting group member to the food building while we moved the car, and as adults such classics as Dawn of the Dead and The Changeling.
The scratchy loud speakers one would hang the driver's side interior window always has bird poop (especially seagull poop) coating it and if the windows were left open, the mosquitoes had a feast. Close them, and the car fogged up (and those burning bug coils set on the dashboard did not work).
