Fun game, some are easy, others a little harder. At one point it stuck me on a pedestrian bridge with no way to move in any direction, so I couldn't try to read a sign to figure out the native language.
I don't know how much Google searching is considered acceptable... the first one was clearly in the American west, but when I saw that all the cars had rear license plates only, I looked up which states didn't require front plates, and the only desert states with no front plates were Arizona and New Mexico, so I was able to get close just by guessing in the middle of the two. On one there was a name of a landmark clearly printed on a sign, and I looked up the landmark and got it close. Don't know if that's considered "cheating" or not.
