This is interesting.
I never gave a minute's thought to where offices of a drive-in theater chain might be located.
Well here's the answer.
eBay
Pacific Drive-In Theatres at 141 - 143 South Robertson Blvd.
, Los Angeles. (1957)
The date is interesting as well. The number of drive-ins peaked the next year (1958) at 4,063 theaters.
