Drive-ins, which were common in the 1950's and 1960's, were great ways to see full-length, feature movies in the comfort of family cars. For the price of admission, about a dollar per car, viewers received a pair of speakers and a parking spot. Carhops (waiters on roller-skates) came by selling candy-corn, ding-dong's, ho-ho's and soft drinks.
Some couples watched movies from the front seat while their small-fry's slept in their pjs in the back seat. Others watched in cars with convertible-top, which were opened up for better viewing. Still others watched from the cargo-bed of pick-up truck, which were parked backwards. Whole families sat in the back with cushions, blankets and lawn chairs.
Unlike theaters where people had to mind their ps and qs, drive-ins were informal and relaxed environments. If you didn't like hearing someone talking during the movie, you rolled up your window.
Intermission breaks were equally amusing. People got out and stretched their legs and chatted with passer-bys. Guys checked out each other's "wheels", and girls admire each other's up-dos. Goes-between introduced guys to girls and vice versa. And some car windows steamed up. (A no-no!)
In the late 1950s, one-third of the theaters in the US were drive-ins; however, now only about 350 remain. Economics, new technology and urban-sprawl have squeezed out the once popular venues.
