A place where my future children can play in the woods?
I grew up in a car-dependent suburban hellscape BUT, it was situated at the very edge of development. Right in our backyards we would just walk into untouched woods and play all day for what seemed like an eternity back then.
I do believe this is ESSENTIAL for childhood. Simply being able to WALK out into nature whenever one feels like it. Not necessarily a place where nature is "close" but is really an hour drive away (car dependent).
The trade off (like where I grew up), is that these edge of suburban developments are car-dependent. My neighborhood was EXTREMELY car dependent, the woods were really the only highlight. Maybe that's why I covet them so much.
Any somewhat dense walkable small, medium, (maybe large) towns where this exists?
"Back-yard woods."
As walkable and bikeable as possible.
No other criteria.
(I'm thinking this may only be achievable outside the United States really. Maybe Europe.)
