Marlboro Speedway, southeast of Washington DC hosted a variety of SCCA events in the mid 60s. It may have never achieved the fame of Lime Rock or Road America or the Glen, but it looks like it was a fun venue, as these photos document. This is from a 12 hour endurance held in the Summer of ’66, but I’m not able to find much additional information on this specific race. Thankfully, these photos from Cliff Rullman highlight the race in wonderful Kodachrome. I love seeing VW Bugs mix it up with Cortinas and Alfas.
