Upon first glance at a sample in the suburbs, I saw that many addresses that could be imported weren't because the address points and the buildings were too far away. Therefore, I bumped up the maximum distance between building and address to 10 meters (approximately 32 feet). Most addresses are (supposedly) located in Roswell, GA, along with some addresses having a city of Atlanta and Alpharetta.
