You weren't kidding when you said old. The vehicles make me want to say somewhere around mid to late 70s?
I'm a beginner, but I like the framing, and the emotional attachment the towers have to us all.
On a personal note, it seems like photos with the towers in them are no where to be found anymore. You hardly see any older photos with them in it anymore. I just think its sad, cause just like a person who has suffered a tragic fate, we should cherish the memories of the people by seeing the buildings. I don't know if that makes any sense, though.
