I love to spend time here. I have been around the world and been to places I would never have had the opportunity to see otherwise. Moscow is my favorite place to visit.
The download is free & doesn't take very long, either.
When we were looking for a job for DH, I'd look up the city we would be visiting. Found the LQS and then looked at the photos of the store. Made it a whole lot easier to find it as I knew what the building looked like and the surrounding area, too. Same with the hotel we had booked, eating places, etc.
