Nice job on the drive-in page. I love those topo photos.
Macon, GA had quite a few drive-ins and the last one closed in the summer of 1984 (Southside Drive-In on US 129S of Macon). It was called the Weis Drive-In during previous years.
North Macon: Riverside Drive-In on Arkwright/Riverside where Carrabba’s is.
West Macon: MotorVue (closed in 1960s; KMart then a furniture store took that space at US80/US41)
East Macon: Dixie Drive-In, closed in mid-70s, off Jeffersonville Road (apartment complex is there now)
South Macon- Weis Drive In and 41 Drive-In (the latter is where a Fed-Ex facility is located).
Warner Robins had a drive-in north of the main gate of Robins AFB off GA247/US129.
If I am not wrong I saw the remains of a drive-in off GA11 near Social Circle, GA. An empty field and a marquee remained as of last year or so.
PS: I couldn’t find the Jesup GA drive-in theater when I drove on US 341 a few months ago. Hmmm….
