I agree that Googling/reverse image searching is "cheating" to the extent that you're no longer using your own knowledge of the world to try to guess a location, but the sheer amount of time and effort Denmark had to undertake to accurately pinpoint a middle-of-nowhere location is impressive (and/or indicative of masochism). It's certainly not a feat that I will try to match, though I enjoy limiting my search to Geoguessr's map and trying to use my own knowledge (and it adds an element of fun when I'm way the smurf off base). Though he's fortunate he didn't get one of those locations where you're stuck in one location and can't move, which has happened twice to me (once on some snowed-in street by a random house and once on a tennis court with people playing on it, weirdly enough).

I don't do no camera pans, though for the first few games I was doing no movement (but allowing zoom). Now I'll move a little bit if I see something potentially helpful, though after a minute or so I give up and guess.
