The Summer Twin Drive-In theater on Summer Ave east of I-40 was opened in 1948 by Kemmons Wilson, the founder of Holiday Inn and bought by Malco theaters in 1966. The popular Memphis summer hangout gradually expanded over the years from 670 cars in 1948, to 1600 in the 1960s, and finally to the current capacity of 2000 cars. The theater also expanded from 1 to 2 to 4 screens over the years, becoming known today as the "quartet". Based on the films being shown, this photo is probably from 1962. Luckily, 21st century Memphians can still enjoy this quintessential automobile-age theater experience.
