Currently Ostpark doesn't include the soccer fields, but from the description in Wikipedia ( https://de.wikipedia.org/wiki/Ostpark_Frankfurt_am_Main ), it seems like it should.

Is this intentional or should it be changed to include the soccer fields (and all green parts until the A661 in the east and the train tracks in the south)?
