Google added a new feature to detect your current location on your desktop computer.
I tried it this morning and it was smart enough to tell me I am in the state of New York. :)
So I of course fixed it by telling it my exact address:
This differs from Google using your "default location" or from Google enabling you to pull the GPS location off your HTML5 browser and using that location.
The Google Maps team said:
We've recently made it much easier and faster for you to start your journey on Google Maps from your current location. Now, when you visit Google Maps you’ll be automatically zoomed into your city as the starting point for your search. You can dive right in and discover the local businesses, restaurants and attractions near you, without having to manually enter your location.
