Where do the children play?

When the kids were babies we had the standard debate of move to the countryside for fresh air and gambolling in the fields etc. But so glad we stayed in London, the kids have so much freedom with public transport they can organise their own meet ups and activities and go running around all over town without any parental assistance or intervention at all. Whereas elsewhere we'd need to drive them everywhere, they'd be stuck at home way more, they'd have no real agency in their lives - I grew up like that and hated it.
