When you see a photo, particularly an old photo...say of New York or somewhere, or you're watching a film, particularly an old film and you just have to find the location on Streetview?
like I just saw this
And saw that "Spring Street" is on the sign in the background
So I virually twatted the length of Spring Street in New York, stopping at junctions and checking in each direction to see if that's the intersection.
This is stupid isn't it?
