Somewhere, USA, 1960s

While we were able to pinpoint the location of the last trackside carspotting photo that we got from Gmund 356 as Bridgehampton, this one poses a little more of a challenge. Still, there’s probably enough here for anybody familiar enough with SCCA tracks in the Sixties to deduce the place and possibly even the date. So, besides some good racing action and a couple of excellent bubble helmets, what do you see here?
