      On Jan 3rd 2012, the City of Chicago released Plow Tracker, an app that tracks the city's snow plows in real time. We want to thank the city for taking this innovative step towards

      The more data they release, the more useful stuff we can build.

    %h3#what-data-is What exactly does the map show?
    %p The dark lines on the map are road segments that plows have likely driven over since we started tracking them. That's it. We don't know whether they were salting, plowing, or just passing through. And we don't know for sure whether those streets are currently clear, because we don't have info about road conditions. Roads that were plowed early on might accumulate fresh snow as the storm ginds on.

    %h3#dont-sue-us Disclaimer: data may not be accurate
    %p What's more, we don't guarantee that the dark lines — which, again, show where plows have passed - are accurate or complete. We only have data that the <a href='http://www.cityofchicago.org/content/city/en/depts/mayor/iframe/plow_tracker.html'>City of Chicago's Plow Tracker</a> makes available. This means that private plows, modified garbage trucks and smaller vehicles are not tracked. 

    %p The plows we do track only transmit their rough locations, and they don't quite do so in real time. We make a best guess about where plows have passed, but it's still just that: a guess, though hopefully a good one. Don't sue us.

    %h3#lessons What we've learned about plowing in Chicago

    %p After tracking the plow operations for several winters in Chicago, we've learned a few things:

    %ul
      %li 
        %p
          On average, the City does a consistent and amazing job plowing every street in the City equitably and fairly.
      %li 
        %p
          Snow plows will stay on the main arterial streets until it stops snowing. After that, they get to the side streets.
      %li 
        %p
          As far as we know, the City of Chicago does not have official routes for snow plows.
      %li
        %p
          Plow operations are run by the <a href='http://www.cityofchicago.org/city/en/depts/streets.html'>Department of Streets and Sanitation</a>. You can find them on Twitter <a href='https://twitter.com/StreetsandSan'>@StreetsandSan</a>
