Oh look. First world problems. For all you know they might have picked there because that's the one their children like and they new the kids would get upset. There could be million reasons. They might have just been so happy and having fun and not really thought about. Or they might have not given a cr@p. But jeepers, it's just a park. This again reinforces why I don't do parks, mothers groups, play centres or anything that have hordes of women. You just cant do it right.
