No bike paths, just rural roads. Generally without any center line, even. We gave our kids mobile phones early on so they could stay in touch while being independent. It is common for kids in town to go fishing or sailing small boats on their own on a large pond in town. Lots of autonomy.

Were there lots of other children doing the same? Living in eastern Canada I've never really seen what you're describing.

Yes, this was, and still is, normal. Some people do drive their kids to school. But kids are still very independent. It's a small town with spread out houses. The general store, library, after school sports, and the town beach, in warm weather, are the choices of things to do. Things have changed a bit. It's more upscale. Farm dogs don't roam about. Hidden fences are installed most places. That makes life easier for cyclists.
