I am so glad you attempted to discover the timeline: Maybe the cars are from that era, I wouldn't be one to know that, but the shot was taken 2 summers ago! :) When one finds oneself in these locations, it is a bit surreal as it feels so out of time, maybe a solid 50 years earlier, as you predicted. Great guess really! Glad oyu enjoyed and participated in the guessing game too.

Namaste :)
