So it turns out that if you want to get directions to my home home (in Chino Hills), online mapping services are always wrong. For some reason, they put my house up the street from where it actually lies. What’s up with that? More importantly, how do I get it fixed? Mapquest, Yahoo! Maps, and Google Maps all put my house in the same location, so it can’t be them that’s the problem. From whom do they buy their mapping data, and how can I get this problem solved? Anybody have any tips?
