la-county-parks

Could refresh or add based on recently released county data http://egis3.lacounty.gov/dataportal/2016/07/07/park-needs-assessment/

There are also a lot of parks listed as nodes in OpenStreetMap that could be drawn or imported.

Next steps

1. Compare OSM data to county data (using QGIS and Overpass turbo)
2. Tackle MapRoulette challenge fixing any node marked leisure=park
3. Possibly use the county's feature tilelayer to help define perimeters of park.
