Earlier quoted context omitted.
This behavior is probably overrepresented in the bougie places reporters live. I live in Redmond, WA. Bougie? My rube Midwestern ass thinks so. And there are feral kids all over my neighborhood. Plenty of kids walking to school in groups, or solo. Neighbor kids talk about riding the bus/train to places. Granted, there are a lot of immigrant families around here (hello, Microsoft, et al.), and I'm sure that skews thin…
'Feral' seems like an odd choice of word, given the activities you're describing. It sounds like they're just out and about doing totally normal stuff. I bet you wouldn't appreciate someone describing you as 'feral' if they saw you in public walking to the store or getting on a train.
I never said the feral kids were participating in those activities. :-) Look, it was loose use of the word, you're placing way more judgement on the term than was ever intended. Yes, the children have homes and parent, of course they're not feral.
