text: leisure=pitch polygons are allowed to overlap.  A common example would be where you have a baseball field and a soccer field in a park that partially overlap.
  
  leisure=pitch is only used for the actual playing surface and not the whole surrounding area.  In this case, we should have the leisure=pitch on the rectangle for the football field and the object surrounding it could either be omitted (in which case the name "Peter W. Stott Community Recreation Field", along with the surface and lit tags, would be applied directly to the football field.
  
  If you wanted to retain the outer area, you could tag it as leisure=recreation_ground and convert it to a simple polygon and not a donut-shaped multipolygon.
