Just kidding. But lately I’ve been using it to check out places in Peru. Some of the field school students wanted to know where their hostel is located. I scanned over the city of Lima until I found the right place. I guess you can’t tell much about crime and sanitation from the Google Earth view. They should make map overlays for crime and population density like SimCity has. Knowing Google, that’s coming.
I also looked around the country for archaeological sites. Most have been previously marked so it was pretty easy. You can see how huge some of the city-sites like Chan Chan are.
