Ghundred, your photo was about the fourth we’ve had so far in this thread that has not been able to be found by research. It’s often difficult to judge how difficult a photo might be, but they should be able to be found and/or verified independently by using research such as map street view, photo sphere, sat. view, other photos, etc. We’ve all overlooked this at some point in the past, so don't worry about it.
