I see no point whatsoever in making this Route 'efficient'. The only part of the CDR so far that is etficient at all in heading N/S are the gravel roads South of Detroit. I'm just not sure there are any other options that go through on dirt. If the roads "go through" to somewhere, even if, or especially if, it takes the loooong way to the South, and if they are bad-rutty rocky road fun and require no pavement to get to/from......then they meet my standards as a good bad road. I'm in no real hurry when I moto-camp, I just ride like I am.
