In my corner of the state, all Internet connections bottleneck at a single physical cable part of which runs under a highway in a landslide-prone region leading to a connection with the rest of the world. So even if you've got a floating IP and the lookup says you could live anywhere from Oakland to Redding, it's a dead giveaway when the second-- or second-to-last-- stop on your route is always the same place.
Anyway, I give up. After my latest run of experiments with the library's public terminal, I've decided that google simply scans my irises. How they contrive to do this when the library's computers don't even have the camera thingie is a mystery, but I'm not losing sleep over it.
