Same, it said Riverside but I'm in San Diego (about 100 miles away from Riverside).

Of course, its just using a geolocation database for the IP address and thus reporting the location of some switching center Verizon runs and not my actual location.

If you're trying to prove a point about privacy its probably best not to lead off with information that can be off by hundreds of miles while presenting the fact that it "knows" this information as being darkly ominous.

Presenting this information while being wrong probably does the opposite of the site's intent and gives some people a false sense of security because what real websites and apps track about you using digital fingerprinting is a lot more detailed, personalized and (usually) correct than what this website presents.
