Among the many odd things I like to do online (get your minds out of the gutter, bitches!) is find photos taken in the last century and then look up the same location on Google Street View now to see that time has changed. I don't do it that often, because Shorpy (the source of most of the old photos) doesn't always provide exact locations—or at least locations that can easily be found on Street View. But occasionally I luck out as in the photo above: 13th & F Street NW, Washington DC.
