- There is a website out there called historicaerials.com
Lucky for us it covers portions of Maryland. Just type in Marlboro Raceway in their search window and an aerial will appear of the track with the choice of 8 different years.
I starts in 1953 with the earliest configuration, the 1/3 mile dirt oval. Then switch to 1957 and you will see the road course added. The other years available are 1963,1970,1980,2002,2005 and 2006.
