Just saw this, don't know if you've already travelled.
I ride mostly north of the suggested route and don't have a lot of experience on it. It looks reasonable.
Let me know if you'd like my name and number as an "In Case of Emergency" contact. You might not be able to PM me until you have enough posts.
