I was able to grab a street view from Google Earth of the four billboards at those coordinates that I posted. Alas, I don’t have an on-line photo repository so I couldn’t post the photo. Cheers!

Details, please. How did you do it?

Good work. I had narrowed it down to Mongolia along the mountains. The green Chinese roof and Chinese arch in the roadway were clues, plus the blue roof at the bottom is Mongolian. How did you find the exact location?
