Hello, this might be in the hands of the CSV file, but it may also be a bug.

I looked in the CSV file and found San Ramon,California and San Francisco,California.
I also have my coordinates that come up as San Ramon, even though they are in San Francisco.

37.78674,-122.39222,ME
37.77493,-122.41942,San Francisco,California,San Francisco County,US
37.77993,-121.97802,San Ramon,California,Contra Costa County,US

The "ME" point is closer to San Francisco, it shows up as San Ramon. See this image:

ME is blue. San Francisco is green. San Ramon is red.

I understand that coordinates are not in a 2d space, but is there something about the math that is making ME show up as San Ramon?

>>> reverse_geocoder.search([(37.78674,-122.39222)])
[{'name': 'San Ramon', 'cc': 'US', 'lon': '-121.97802', 'admin1': 'California', 'admin2': 'Contra Costa County', 'lat': '37.77993'}]

Thank you.
