Oh yes, my mistake, I was inferring the wrong conclusion from your first comment.

> Most of the roads are still unpaved, but you spend most of your driving time on the paved roads.

Yeah I definitely agree with that. I imagine if you were to look at my county's roads from a satellite, it'd be something like the (grid-shaped) veins of a leaf — the thick, prominent veins are the paved roads, providing the structure, while the thinner, branching veins are the gravel roads that run between them.
