Who made the road maps? Are they really free?
The United States Census Bureau created a database of roads and and other geographic features in order to facilitate their monumental task of tracking down every man, woman, and child and asking them to fill out a short questionnaire. Because U.S. taxes paid for the map data, it makes sense that they would not charge for it a second time. That logic apparently doesn’t apply in other parts of the world, or there would be international versions of 93 Photo Street.
