Oh yep, I try to find the same place on Google Street and also the same angle. Then I capture the image, cut it out and give it the approximate size.
I love those comparisons.
I had family in both sides. Fun story: Mi great-grandfather was a left wing basque nationalist engineer that had his quite numerous properties in Pamplona confiscated never to be seen again. It was also arrested and his name written on a "to be shot" list. A relative, which was a falangist with a bit of authority, saw the list on the detention camp and simply erased the name, thus saving his life. This really shows in my opinion how much of a "war between brothers" it was.
