> Your kids are hardly free-range. Let me guess, there's no way for them to actually meaningfully leave the area (no train, bus, etc)? It's like dumping kids on a 5 acre farm and saying they can do whatever they want. hardly free-range in the way described in the article.
This depends on the area. In more urban areas exploring can be done on foot or bike. I live in Seattle, which has some fantastic bike trails that can go on and on for miles and cross into multiple adjacent cities.
In some cities parents are fighting to let their kids play in their own front yard unsupervised. Not an issue in Seattle, where kids are required to walk to and from their neighborhood school by the school district.
But denser areas also have lots of stuff to do within the neighborhood. Within 2 or so miles there is a massive shopping area, multiple bakeries, tons of restaurants, a slew of parks (Seattle has an obscene density of parks, it is one of the best aspects of living here), a lakefront beach (lots of bodies of water in Seattle), 2 swimming pools, tennis courts, and a bunch of other stuff I am probably forgetting right now.
So define free range. If a gaggle of kids travel to the local grocery store together to buy lemons and sugar, then self organize selling lemonade to people passing by on a hot day, is that free range? I'd argue yes.
