title: Geocoder gem not displaying proper distance users are away from address
body: <p>I am using the geocoder gem to implement geolocation in my rails app.  I am geolocating by address.   The users are displayed properly according to location on the map but the distance away is incorrect.  When the user index is displayed following the search the users are all set to 250.00 to 253 miles away even though they should all be 1 or 3 miles away from the address I have saved as a user.  Any reason why this would be the case and how I can fix it? Also, when I attempt to search for the users nearby, all the users are being picked up, I have 100 miles declared in the index controller and if I put a user 1000 miles away they are picked up as well. How would you set it so that only users within the 100 miles radius are picked up? Any help would be greatly appreciated, thanks!</p>
