co-op
But....but cLoWnFiSh....
The rec is dominated by older hard lads, where they, especially young girls, feel uncomfortable - one of the few spaces where certain older teens/young adults feel they can control their surroundings. Not everyone can live in a sub-system where a dose of charity/mutual aid can put things rights.
Where I live every playground is definitely "owned" by a gang of some sort (i.e. not a formal gang but a loose group). I have had real issues trying even to use pre-booked and paid for pitches for football coaching because some of my boys do not feel safe going to them even with adults. It's been a real problem. (and my coaching is definitely mutual aid, I don't get paid). It depends alot on time of day etc, I wouldn't want to overstate it - certainly for me, but for kids safe space barely exists in cities now outside their own houses.
