I find that there are not enough designations for rural roads. There are certainly many grades of rural roads in our area, which is intensively settled. I've found 'minor ones' in a few places too. So there are tertiary which in my schema "go places" - not necessarily a town - then unclassified and tracks, with paved and unpaved as modifiers.
