Forgot to add in a bit of detail about day 5. After I left the dam, the GPS told me of a shorter route. Turns out that route was partially constructed by an oil/gas and forest service road. It was about 40-50 miles of poor dirt road with trucks coming the other way every 5 or 10 minutes.
Here is a bridge along the way
About 1/2 way along the road I really wished I had taken the slightly longer route.
